Welcome to Anping County Boli Hardware Wiremesh Products Factory — a trusted manufacturer since 1998, specializing in high-performance filtration solutions. Our Pleated Dust Filter Cartridge 350gsm Polyester, 32x32x26 Inches is engineered to deliver exceptional dust capture in industrial environments. With a filtration efficiency of 99.9%, this cartridge is ideal for heavy-duty dust collectors used in mining, cement, woodworking, and chemical processing. We combine decades of manufacturing expertise with rigorous quality control to ensure your operations run cleaner and more efficiently.
Our polyester pleated filter cartridge stands out due to its 350gsm high-density felt — a robust material that resists abrasion and maintains stable performance even under high dust loading. The pleated design dramatically increases the filtration surface area, allowing for higher airflow and longer service life between replacements. Each cartridge is precisely cut to 32x32x26 inches, fitting most standard industrial dust collector housings. The 99.9% efficiency rating ensures that even fine particles (down to sub-micron sizes) are captured, protecting both equipment and the environment.
Key Features & Technical Specifications
- High-Grade Polyester Felt: 350gsm weight provides excellent tensile strength and resistance to moisture, chemicals, and heat (up to 150°C continuous operation).
- Optimized Pleat Geometry: Deep pleats (50–60 pleats per cartridge) maximize media area while minimizing pressure drop, improving energy efficiency.
- 99.9% Filtration Efficiency: Tested per ISO 16890 and EN 779 standards (equivalent to F9 class), capturing particles as small as 0.3 microns.
- Standard Dimensions: 32" (W) × 32" (D) × 26" (H) — compatible with many pulse-jet dust collectors.
- Durable Construction: Galvanized steel end caps and inner support cage prevent collapse under high differential pressure.
- Easy Installation: Includes gasket seal to prevent bypass leakage; drop-in replacement for most cartridge systems.

Beyond the raw numbers, our pleated filter cartridges offer tangible benefits to your operation: reduced energy consumption thanks to lower pressure drop, fewer filter replacements due to the robust 350gsm media, and improved air quality that helps you meet regulatory emission limits. The square 32×32 inch design fits readily into existing pulse-jet collector systems, and the 26-inch height provides ample media area for high-volume applications. Whether you are handling cement dust, sawdust, metal powders, or chemical fines, this cartridge delivers consistent performance.

Frequently Asked Questions
-
What is the typical lifespan of this cartridge?
Depending on dust load and cleaning frequency, the cartridge can last 6–12 months in moderate conditions. With proper pulse-jet cleaning, it may last up to 2 years. -
Can this filter be washed or reused?
Yes, the polyester media is washable with low-pressure water (max 3 bar) and mild detergent. However, efficiency may slightly decrease after multiple washes. We recommend replacing after 2–3 washes. -
What is the maximum temperature the cartridge can handle?
Continuous operation: 150°C; intermittent peaks up to 180°C. For higher temperatures, we offer alternative media (e.g., PTFE membrane) — please inquire. -
Are these dimensions compatible with Donaldson® or Camfil® housings?
Yes, the 32×32×26 inch size is a standard industry dimension and fits many popular pulse-jet collector models. We recommend verifying your housing’s mounting hole pattern before ordering. -
Do you offer a money-back guarantee if the efficiency is not 99.9%?
We stand by our test results. Each batch is tested per ISO 16890; we can provide a certificate of analysis upon request. If a defect is found, we will replace the cartridge. -
Can I get a sample before placing a bulk order?
Absolutely. We offer sample cartridges (1–2 pieces) at a reasonable cost, with shipping via express. The sample cost is deductible from your first bulk order. -
What is the lead time for a standard order?
For 100–500 pieces, typical lead time is 15–20 days after deposit. Larger quantities may require 25–30 days. Express shipping is available for urgent orders. -
Is this cartridge suitable for food-grade applications?
The polyester media is FDA-compliant for indirect contact. However, if you need direct contact with food, we recommend our PTFE-coated version. Please consult our sales team.
