Detailed Description
How much air can the same 610×610 opening handle?
The deeper the filter and the more media it holds, the more air it can pass. The chart shows rated airflow and initial pressure drop for each version in the same 610×610 mm opening:How much air can the same 610×610 opening handle?
Rated airflow and initial pressure drop (supplier quotations and model ratings)
The 150 mm high-capacity value is scaled by area from the 23.4 CMM of the 570×570 model. Values come from different quotations and model ratings and show the trend; the shipping specification governs.
| Version | Depth | Rated airflow | Initial pressure drop |
|---|---|---|---|
| Mini-pleat HEPA (for comparison) | 70 mm | About 10 CMM | About 123 Pa |
| Aluminum separator, standard | 150 mm | 17.0 CMM | About 249 Pa |
| Aluminum separator, high capacity | 150 mm | About 27 CMM | About 249 Pa |
| Aluminum separator, standard | 292 mm | 32.6 CMM | About 249 Pa |
| Aluminum separator, high capacity | 290 mm | 56.6 CMM (2000 CFM) | About 333 Pa |
Standard vs high capacity
The high-capacity version folds more media into a frame of the same size, so the same opening passes more air. At 150 mm depth, the high-capacity version has the same initial pressure drop as the standard, about 249 Pa; at 290 mm depth, airflow rises from 32.6 CMM to 56.6 CMM and pressure drop from about 249 Pa to about 333 Pa. Actual values for other sizes:| Frame size (mm) | Version | Rated airflow | Initial pressure drop |
|---|---|---|---|
| 610×1220×150 | Standard | 35.4 CMM (1250 CFM) | About 249 Pa |
| 570×570×150 | High capacity | 23.4 CMM | About 249 Pa |
| 570×1170×150 | High capacity | 49.4 CMM | About 249 Pa |
| 305×305×290 | High capacity | 11 CMM | About 333 Pa |
Frames, gaskets and other options
- Frame: wood, galvanized steel, aluminum or stainless steel (SUS304/316) - Gasket: outlet side, inlet side, or both sides - Depth: most commonly 150 mm (about 5⅞″) and 290/292 mm (292 mm is about 11½″); also 266, 300 and 305 mm - Width and height: besides the 305 and 610 series, many non-standard sizes are made - For hot environments there are 150–300°C stainless-frame versions; see the high-temperature filtersWhere it is used
- The final (HEPA) stage of air handling units for cleanrooms and clean areas - Where high airflow is needed and the AHU has enough depth; where depth is limited, use a mini-pleat HEPA insteadFrequently Asked Questions
In the same 610×610 opening, how much air do the 150 and 290 mm, standard and high-capacity versions handle?
150 mm standard is about 17.0 CMM and high capacity about 27 CMM, both at about 249 Pa initial pressure drop; 292 mm standard is about 32.6 CMM at about 249 Pa; 290 mm high capacity is about 56.6 CMM (2000 CFM) at about 333 Pa. For comparison, a 70 mm mini-pleat in the same opening handles about 10 CMM at 123 Pa at 0.45 m/s. The US Department of Energy standard DOE-STD-3020 rates a 610×610×292 HEPA at 1000 CFM with a maximum pressure drop of 250 Pa, which can serve as a reference.
The specification says 290, 292 or 300 mm. Does it matter?
Yes — measure how deep the frame on site actually allows. 292 mm is the metric equivalent of 11½″, while 290 mm is a common metric depth; we make both, plus 300 and 305 mm. Customers have specified depths such as 250 or 310 mm, which are not standard for us and need to be confirmed. When replacing, measuring the actual depth of the old filter is the most reliable.
The specification says "EN 779 H13". Can you supply that?
The wording itself is inconsistent: EN 779 only has G, M and F classes and was replaced by ISO 16890 in 2018; H13 is an EN 1822 class requiring overall efficiency of 99.95% or higher. Our aluminum-separator filters are rated by efficiency at 0.3 μm (95–99.99%). If your specification requires EN 1822 H13 with a classification report, please say so in your inquiry and we will select accordingly.
For the same 610×610×290 size, how do I tell an aluminum-separator filter from a V-type?
Look from the side: the aluminum-separator type is one block of deeply pleated media with corrugated aluminum strips between the pleats; a V-type has several thin mini-pleat panels arranged in a V, with no aluminum strips. Both can share the same frame size but differ in pressure drop and airflow — for example, one 610×610×290 V-type is rated at 50 CMM at about 249 Pa. The size alone is not enough to tell them apart, so please include a photo of the old filter with your inquiry.
Can you make non-standard sizes such as 590×590×250?
Width and height, yes — besides the 305 and 610 series we have made many non-standard sizes, such as 289×595, 525×505 and 700×700. Depth is more limited: standard depths are 150, 266, 290, 292, 300 and 305 mm, and a depth such as 250 mm must first be confirmed with production. Please give width × height × depth, efficiency, frame material, which face the gasket is on, and the quantity.
