This industrial air filter cartridge is designed for high-efficiency air filtration in applications requiring fine particle removal and reliable structural support. With an outer diameter of 114 mm, a height of 213 mm, and a G1 inch female threaded connection, it can be customized to meet different equipment installation requirements.
The filter features 304 stainless steel end caps and a 304 stainless steel diamond mesh outer support cage. These components provide structural stability and help protect the filter media during operation. Two filter media options are available: H14-grade fiberglass media with inner and outer support mesh, or membrane-coated polyester fabric. The appropriate option can be selected according to the required filtration efficiency, operating environment, airflow conditions, and dust characteristics.

1. H14-Grade Efficiency, Independently Classified
Rated H14 under EN 1822 — ≥99.995% integral separation efficiency at MPPS (0.1–0.3 μm). One order of magnitude lower penetration than H13, making it suitable for ISO 5 cleanroom supply air, sterile filling lines, and terminal filtration where sub-micron control is non-negotiable.
2. All-304 Stainless Steel Construction
Both end caps and the outer diamond-mesh cage are 304 stainless steel. No plating to flake, no aluminum oxide shedding into the downstream airstream, and no media migration under differential pressure. The diamond-mesh pattern provides superior pleat support compared to expanded metal and holds its shape through repeated pressure cycling and humid operating conditions.
3. Hybrid Glass Fiber + PTFE Membrane Polyester Media
An H14 borosilicate glass fiber layer delivers depth filtration and mechanical capture, while a PTFE membrane laminated to polyester cloth acts as a hydrophobic surface barrier and drainage layer. The result: high efficiency plus resistance to moisture-induced pressure spikes — a common failure mode for all-glass-fiber HEPA elements in humid compressed air lines. Internal and external support nets keep the pleat pack rigid under pulse cleaning and pressure surges.
4. Compact 114 × 213 mm Envelope
A tight form factor that fits standard housings designed for this element size, ideal for equipment cabinets and skids where installation space is constrained. Measure your housing ID and available height before ordering — allow 3–5 mm clearance.
5. G1" BSPP Female Connection
Standard British parallel pipe thread, widely used in European and Asian industrial air systems. Directly compatible with G1" male fittings. Note: not interchangeable with NPT 1" without an adapter — the thread forms differ (parallel vs. tapered).
Application Fit
Pharmaceutical & biotech: sterile filling, fermenter inlet protection, cleanroom supply air
Compressed air precision filtration: terminal sub-micron and oil-mist removal downstream of refrigerant dryers
Food & beverage: H14 particle control for air contacting product or packaging; all-metal support structure eliminates fiber-shedding risk
Electronics & semiconductor: terminal filtration for ISO 5 workstations and wafer transfer zone
We provide customized air filter elements for different industrial filtration requirements.
Q1: What filter media are available for this industrial air filter cartridge?
A: This air filter cartridge is available with H14 fiberglass media supported by inner and outer mesh, or membrane-coated polyester fabric. Customers can select the appropriate media according to filtration requirements, airflow conditions, dust characteristics, and operating environment.
Q2: Can you customize the dimensions and connection type of this air filter cartridge?
A: Yes, TOPEP provides customized air filter cartridges according to customer drawings, samples, or equipment specifications. Outer diameter, height, filter media, support structure, and connection type can be adjusted to meet different installation requirements.
Q3: What are the advantages of the 304 stainless steel end caps and support cage?
A: The 304 stainless steel end caps and diamond mesh outer cage provide structural support and help maintain the cartridge's shape during operation. They are suitable for applications requiring a stainless steel construction, subject to the operating environment and material compatibility.
Q4: Does the H14 fiberglass filter provide high-efficiency air filtration?
A: H14 is a high-efficiency particulate air filtration classification used for qualifying filter products. The actual filtration efficiency should be confirmed through testing according to the applicable standard, while the coated polyester option requires separate performance evaluation.
Q5: What is the function of the G1 inch female threaded connection?
A: The G1 inch female threaded connection allows the cartridge to be installed in compatible filter housings or filtration equipment. Before ordering, customers should confirm the thread standard, available installation space, and sealing requirements to ensure a proper fit.
Q6: What applications can this industrial air filter cartridge be used for?
A: This cartridge can be considered for compatible industrial air filtration systems and selected fine-particle filtration applications. The final filter media should be chosen according to the required filtration efficiency, airflow, dust loading, temperature, humidity, and equipment operating conditions.
Q7: Can TOPEP manufacture replacement air filter cartridges based on an existing sample?
A: Yes, TOPEP can evaluate replacement filter cartridges based on an existing sample, technical drawing, or original equipment model. Providing dimensions, connection details, filter media requirements, and operating conditions helps us assess compatibility and recommend a suitable solution.
