A G3 pleat filter with dimensions 595×595×94 mm is a coarse pre-filter commonly used for HVAC and cleanroom applications, designed for high dust holding and low pressure drop.
Key Specifications grade: G3 (EN779 standard, coarse filter for particle sizes 0.5–10 micron).
Dimensions: Standard size for pleated panel filters includes 595×595×96 mm, which is the closest to 595×595×94 mm and is commonly available.
Air Flow: Rated for approximately 3400 m³/h for the 595×595×96 mm size.
Initial Resistance: 35 Pa (for 595×595×96 mm G3 filter).
Final Resistance: 200 Pa.
Frame Material: Options typically include galvanized steel, aluminum, or stainless steel.
Media: Usually synthetic polyester fiber or glass fiber.
Usage: Suitable for pre filtration in HVAC systems, cleanrooms, paint booths, and as a first-stage filter to prolong the life of higher-efficiency filters.
Common Features disposable or reusable frame, with easy replacement media options.Pleated design increases filter area and dust holding capacity.
Meets ISO16890 or EN779 standards for air filtration.
