1. Filter Frame/Housing
Function: Support filter element/filter cotton, ensure structural stability, and prevent medium deformation or leakage.
Material: 304/316 stainless steel, anodized aluminum (corrosion-resistant and pressure-resistant).
Application: Suitable for HEPA/ULPA filter elements, used in clean rooms and HVAC systems.
Advantages: Modular design, compatible with multi-size filter elements; meets ISO 14644 sealing standards.
2. Filter Cartridge
Type:
Primary filter element: polyester fiber/metal mesh, intercepting ≥5μm particles (protecting the rear high-efficiency filter element).
High-efficiency filter element: HEPA (99.97% @0.3μm), ULPA (99.9995% @0.12μm).
Activated carbon filter element: adsorbs VOCs and odors (chemical/medical industries).
Advantages: washable (metal filter element), low resistance design, extended replacement cycle.
3. Filter Pad/Prefilter
Function: primary filtration, intercepting large particles, hair, dust, and extending the life of high-efficiency filter elements.
Material: synthetic fiber cotton (flame retardant grade), glass fiber (high temperature resistant).
Application: air purifier, industrial waste gas pretreatment.
Advantages: high dust holding capacity, customizable density (such as G3/G4 standard).
4. Quick-Release Clamps
Function: quickly lock the filter element/filter frame to ensure sealing and simplify the maintenance process.
Material: PP plastic (lightweight), stainless steel (high pressure resistant scene).
Application: pharmaceutical/food production line with frequent filter element replacement.
Advantages: tool-free disassembly, in line with FDA hygiene standards.
5. Carrying Handle
Design:
Embedded handle: integrated into the side of the filter frame for easy handling of large filters.
Folding handle: saves space and is suitable for compact equipment (such as portable purifiers).
Material: anti-slip rubber coating, stainless steel reinforcement.
Advantages: ergonomic and reduces the risk of installation loss.
6. Flange
Type:
Flat-weld flange: general type, used for low-pressure pipelines (ANSI 150#).
Butt-weld flange: high-pressure/high-temperature scenarios (ANSI 600# and above).
Material: galvanized carbon steel, 316L stainless steel (acid and alkali resistant).
Seal: silicone/EPDM gasket, suitable for -40°C~150°C working conditions.
