Technical Data
The technical data includes upstream velocity, pleat depth, filter class, nominal volume flow, initial differential pressure, filter area, and weight. Detailed tables are provided for various frame types and configurations.
Example table structure:
| Filter class | Upstream velocity | Pleat depth [mm] | 20 | 46 | 50 | 58 | 68 | 70 | 73 | 90 | 120 | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| ePM10 55% | 2.57 m/s | 90 Pa | ||||||||||
| ePM1 65% | 2.57 m/s | 110 Pa | ||||||||||
| ePM1 90% | 2.57 m/s | 150 Pa | ||||||||||
| E11 | 0.90 m/s | 125 Pa | 135 Pa | 125 Pa | ||||||||
| H13 | 0.90 m/s | 250 Pa | 270 Pa | 250 Pa | 215 Pa | 195 Pa | ||||||
| H14 | 0.45 m/s | 115 Pa | 110 Pa | 95 Pa | 90 Pa | 85 Pa | 80 Pa | 75 Pa | 70 Pa | |||
| U15 | 0.45 m/s | 130 Pa | 115 Pa | 105 Pa | 100 Pa | 95 Pa | 80 Pa | |||||
| U16 | 0.45 m/s | 140 Pa | 125 Pa | 120 Pa | 115 Pa | 105 Pa |
Note: With a pleat depth of 20 mm, the upstream velocity is 0.45 m/s.
The nominal volume flow is the product of the associated upstream velocity and upstream face area of the filter (B x H), minus the profile thickness.
Construction
Frame versions are made from extruded aluminium sections with various frame depths and profiles, including those for continuous seal, flat seal, fluid seal, and knife edge profiles.
Materials and Surfaces
- Filter media made of high-quality, wet-strength glass fibre papers, pleated.
- Spacers made of thermoplastic hot-melt adhesive provide a uniform spacing of the pleats.
- Joint sealing compound made of permanently elastic two-component polyurethane adhesive.
Standards and Guidelines
Testing of particulate filters is conducted according to DIN EN 1822-1 and DIN EN ISO 29463-2 – DIN EN ISO 29463-5. Standards for testing filtration performance at the manufacturing plant are based on particle counting methods using a liquid test aerosol. Testing in accordance with DIN EN ISO 16890 is also applied for air filters for general ventilation.
Order Code
The order code is structured to specify various parameters of the filter, including type, filter class, separation efficiency, construction, upstream side seal, nominal size, pleat depth, protection grid, seal type, testing, and laminar distribution fleece.
Example Order Code: MFPCR-H14-ALC-R/1220×610×78×58/PD/CSD-11/ST/LFD
This translates to:
- Type: MFPCR - Mini Pleat filter panel for clean room technology
- Filter class: H14 according to DIN EN 1822
- Construction: ALC - Frame with groove for foamed seal (depth 78 mm)
- Section upstream side: R - reverse execution
- Nominal size [mm]: Width 1220, height 610, depth 78
- Pleat depth [mm]: 58
- Protection grid: PD - Protection grid on the downstream side
- Seal: CSD - Continuous seal on the downstream side
- Seal type upstream side: Continuous seal foamed in groove
- Testing: ST - Scan test
- Laminar distribution fleece: LFD - full-surface laminar fleece, downstream side
Dimensions and Profiles
The document provides detailed tables and diagrams for various filter dimensions and profile types, including:
- Profiles with groove (e.g., ALD, ALB, ALC, ALG, ALJ)
- Flat profiles (e.g., ALN, ALZ, ALY)
- Profiles for fluid seal (e.g., ALV, ALU, ALQ, ALT, ALH)
- Profiles with knife edge profile (e.g., ALL, ALS, ALR, ALX)
Each profile type is associated with specific dimensions, possible pleat depths, and corresponding technical data such as inflow velocity, volume flow, and differential pressure.
