A buyer who has chosen the format still cannot price a pleated panel from a size label alone. The quotation needs a controlling dimension, a class claim with its test basis, an airflow the panel must pass, and a frame the housing will accept. Pleated panel filter specifications are the field list that turns “24×24, G4” into an order a factory and a receiving inspector can both check.
This article walks each field using Airy’s published pleated pre-filter sheet. It covers the AR-ZK models, their four sizes and rated airflows, the G3 and G4 figures, frame choices, and the resistance numbers. Where the sheet stays silent, the text marks the gap as a question for the supplier instead of an assumption.
Key Takeaways
- Four published sizes: 595×595, 595×495, 495×495, and 595×295 mm faces at 46 mm depth, each with its own rated airflow.
- Grade example: the 595×595×46 mm row lists 85% en 35 Pa for G3, 90% en 45 Pa for G4, y 250 Pa recommended final.
- Order fields: tolerance, marco, caza de focas, and test method are written confirmations to request, not catalog facts.
Which Filtration Stage and Housing Is the Filter For?
Every spec field means something only after the stage is fixed. Name the position first.
Airy’s page places the pleated pre-filter in the primary filtration stage of air conditioning systems, ventilation systems, and clean engineering. The typical applications named on the page run from commercial building air quality to industrial manufacturing, Instalaciones de atención médica, and transit infrastructure. A panel ordered for a different stage inherits the wrong assumptions about dust load and change-out. Name the position and what stands downstream of it on the same line of the sheet.
The housing side is the slot. Fix the face opening, the usable depth around 46 mm, and how the door or track clamps the frame before any efficiency discussion. If you are still weighing formats, see our pocket filter vs pleated panel filter comparison.
Write the stage and housing summary in one line at the top of the specification. That line is what a supplier’s engineer reads before the numbers, and what an inspector checks when two lots look identical. Every other field in pleated panel filter specifications hangs off this sentence.
Stage also steers price. Primary panels buy area cheaply and change often, while downstream media buys efficiency and lasts longer. A specification that names the wrong stage attracts a quotation for the wrong product, and both sides believe they are saving money.
How Should Actual Dimensions and Frame Depth Be Specified?
Publish the millimeter truth. A nominal label is a nickname, not a dimension.
The AR-ZK sheet lists actual panel dimensions in millimeters, with a 46 mm depth across all four sizes: 595×595, 595×495, 495×495, and 595×295 mm faces. Inch-market buyers order against labels like 24×24, so the order sheet should carry the millimeter figure, the requested label, and a note marking which one controls production. The published sheet lists no inch equivalents, so request the nominal name and its tolerance in writing.
Depth deserves its own line because 46 mm is a tight tolerance subject. State the slot depth, the acceptable panel variance, and who measures with what tool. Airy publishes no tolerance on the product page, so the number must come from the supplier’s written confirmation, not from catalog arithmetic. A stated variance also tells the receiving inspector exactly what to reject on arrival.
Ask for the drawing back. This is where pleated panel filter specifications stop being labels and become drawings. The supplier’s sheet shows the frame profile and depth exactly as they will build it. Your approval then sits on that document, not on an email sentence.
What Media, Marco, and Sealing Details Should Be Confirmed?
Medios de comunicación, marco, and seal are three order fields, not one product name.
The page describes the media as polyester fiber or non-woven filter material, pleated to build a large filter area inside a shallow panel. Its listed features include large dust holding capacity, low initial resistance, and washability, without stating which frame configurations tolerate washing, the method, or post-wash performance. Copy each claim you intend to rely on into the specification as a requirement. Put washability, wash method, and post-wash verification on the RFQ question list instead of assuming a cleaning routine.
The frame is a functional choice. The sheet names waterproofing chipboard, aleación de aluminio, and galvanized sheet, and the page does not map each material to a humidity or chemical condition. State which frame the order carries and the reason engineering accepted it, and ask the supplier to challenge the choice if the application disagrees.
Sealing is the silent field. The published page lists no gasket option, so confirm gasketed or gasketless, the clamping method, and the acceptable frame-to-housing gap in writing. A panel that fits the slot but leaks at the edge under-delivers the efficiency its own label promises.
Marking is a spec field too. State what must appear on the frame or media: model code, calificación, airflow direction, and production date. Printing rules look cosmetic until a dock inspector has to separate two grades that share one box size.
Which Efficiency Grade and Test Evidence Are Required?
A grade without a method is marketing. Specify the number and the evidence together.
The sheet sells the line under a G3/G4/MERV 5-8 title and publishes two grades. AR-ZK-G3 carries 85% average arrestance; AR-ZK-G4 carries 90%. Those are the page’s figures, and the page does not name the test method behind them. The specification should ask for the method, the particle basis, and the report format that accompanies each lot.
Keep mixed labels honest. G and MERV notations come from different rating families, and the product title uses both. If your project engineer specifies one notation, state it on the order and require the supplier to restate the same notation on the datasheet. The same rule protects spares stock: two cartons labeled in different notations may be the same product, or may not.
Judge ratings in system context. El ASHRAE filtration and disinfection FAQ supports one principle: filter performance must be judged together with the airflow and condition of the installed system, not from a label alone. That source backs the principle only; it does not test, rate, or certify any Airy model.
How Should Rated Airflow and Pressure Drop Be Compared?
flujo de aire, initial resistance, and the recommended final figure form one locked set. Quote all three.
Airy lists 3,200 m³/h and 35 Pa initial resistance for the 595×595×46 mm AR-ZK-G3 example. The G4 example lists the same rated airflow at 45 Pensilvania. The page also publishes three other sizes with rated airflows of 2,700, 2,200, y 1,600 m³/h. Request the pressure-drop data and test conditions for the exact size being ordered. Both grades list 250 Pa as a recommended final resistance, which should be checked against the project’s maintenance requirements rather than applied as a fixed limit.
| Attribute | AR-ZK-G3 | AR-ZK-G4 |
|---|---|---|
| Average arrestance (page) | 85% | 90% |
| Resistencia inicial (595×595×46 example) | 35 Pensilvania | 45 Pensilvania |
| Recommended final resistance | 250 Pensilvania | 250 Pensilvania |
Figures as listed on Airy’s pleated pre-filter product page. The resistance and 250 Pa values appear on the 595×595×46 mm model row. The page does not state the underlying test methods.
Compare suppliers at your duty, not at their headline. Put the position’s design airflow beside the rated figure: running a panel above its rated airflow moves resistance up and invalidates quiet comparisons. Where a project needs an airflow between published sizes, ask for measured data at that point before shortlisting.
Commission the numbers. When the first panels go in, measure the pressure drop across each filter. Record the actual airflow, the measurement location, and the test conditions before comparing with the sheet. A gap can come from the fan setting, the instrument point, or the media itself, so diagnose those causes before redrawing the duty point.
What Sample, Inspección, and RFQ Details Close the Order?
The sample proves the sheet. The RFQ makes every quote answer the same sheet.
Approve One Sample Before Any Bulk Line
Measure the first panel against the approved drawing, seat it in the real housing, and record the clean resistance at the position’s airflow. Keep that unit and its date as the lot reference. Agree the incoming-inspection items, the sampling frequency, and the required reports in the purchase order. Check each delivery against that written list and the retained sample, and note deviations in writing before warehousing.
Send an RFQ That Competes on the Same Page
A comparable request lists the stage and housing line, the controlling millimeter size, and the media and frame choice. It then adds the grade with its test evidence, rated airflow with initial and final resistance, quantity, and packing terms. Airy’s sheet notes that other specifications can be customized according to requirements. Treat non-standard depth or print as a drawing exchange with a lead-time question, not a checkbox. The wider guide to sourcing HVAC filters from China covers the supplier checks that wrap around this field list.
Two quotes only compete when every field above matches. If one vendor answers with a label and the other with measurements, send the field list back and require both to fill it in.
Keep the completed field list as the purchase specification revision, and attach it to every later order. Re-issue it when the housing, the fan setting, or the grade changes. Silence on a field is a supplier decision, not a buyer saving.
Preguntas frecuentes
What details belong on a pleated panel filter RFQ?
List the filtration stage and housing, the controlling millimeter dimensions, and the media and frame material. Add the efficiency grade with its test evidence, flujo de aire nominal, initial and final resistance, quantity, and packing terms. Ask each supplier to confirm every field in writing so the quotations arrive comparable rather than poetic.
Is nominal size the same as actual size?
No. A nominal label such as 24×24 is a trade name for a class of openings. The actual size is the manufactured panel dimension, and Airy’s published sheet lists millimeter figures only, without inch labels. Mark which one controls on the order, and have the supplier restate the controlling number in the confirmation.
How do I compare pressure drop at different airflow ratings?
Move the comparison to your duty point. A 35 Pa initial figure belongs to the panel’s own rated airflow, so placing two sheets side by side only works when their airflows match. Ask each supplier to state resistance at the airflow your position actually moves, in writing, before you rank the offers.
Pensamientos finales
Pleated panel filter specifications earn their keep when each field is testable. Record the controlling millimeter size, name the media and frame, tie the grade to a stated method, and quote the airflow-resistance set at your duty. The retained sample then referees every later lot against that sheet.
The figures above come from the pleated pre-filter page inside the Panel y filtros plisados category, and the wider lineup sits on the Filtro de aire site.
Turn the Field List Into a Quotation
Submit the filter drawing, required efficiency, flujo de aire nominal, frame details, and planned quantity. Ask Airy to confirm the matching model, the data available at your duty, and the sample terms before bulk ordering.
