As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Custom Coarse Air Filter Bag with PLC Core – engineered specifically for spray booths and industrial dust control applications. Our decades of experience in wire mesh and filtration products, combined with an annual export value of US$5–10 million, ensure that every filter bag meets rigorous quality standards. This product is designed to capture coarse particles effectively while integrating seamlessly with modern PLC-controlled systems, offering you a reliable and customizable solution for cleaner air and compliance with workplace safety regulations.
Product Overview
The Coarse Air Filter Bag features a unique PLC core – a structural support element that can be connected to automated control systems for monitoring pressure drop or filter life. It is ideal as a pre-filter in spray booths to trap overspray, dust, and large particulates before they reach downstream high-efficiency filters. The bag design maximizes surface area, extending service life and reducing maintenance frequency. Customizable dimensions, materials, and filtration grades allow you to tailor the filter to your specific equipment and environment.
Key Features & Technical Specifications
- High Dust Holding Capacity – The bag structure offers up to 3–5 times more surface area than flat filters, allowing longer intervals between replacements.
- PLC Core Integration – A rigid, perforated core (available in galvanized steel or plastic) can be fitted with a sensor port for differential pressure monitoring, enabling predictive maintenance.
- Customizable Filtration Efficiency – Available in G1 to G4 efficiency classes (coarse) per EN 779, with optional anti-static or flame-retardant treatments.
- Durable Construction – Stitched seams with reinforced thread, anti-tear fabric, and a sturdy header plate for easy installation.
- Wide Operating Temperature Range – Standard materials withstand up to 80°C (176°F), with high-temperature options (up to 150°C) available upon request.
- Low Pressure Drop – Optimized airflow design ensures minimal energy consumption while maintaining capture efficiency.
- Eco-Friendly Disposal – Filter media can be incinerated or recycled, depending on material selection.

Benefits for Your Business
- Reduced Energy Costs – Low initial resistance and high dust holding capacity mean less frequent fan speed adjustments, saving electricity.
- Extended Final Filter Life – As a pre-filter, it captures the bulk of coarse particles, protecting downstream HEPA or carbon filters.
- Smart Maintenance – The PLC core allows integration with building management systems (BMS) for real-time filter status, reducing labor and downtime.
- Compliance Assistance – Helps meet OSHA and local air quality standards for spray booth exhaust and industrial dust collection.
- Custom Solutions – We can tailor the bag dimensions, media type, efficiency, and core material to fit your existing housing or retrofit projects.
- Fast Delivery – With our factory located in Hengshui, Hebei, and ports like Tianjin and Qingdao, we offer efficient global shipping.

Frequently Asked Questions
-
What is the difference between a standard bag filter and one with a PLC core?
A PLC core includes a rigid support structure that can be equipped with a sensor port, allowing the filter to be connected to a programmable logic controller (PLC) for automated pressure drop monitoring. This enables predictive maintenance and alerts when the filter needs replacement. -
Can I use this filter bag for high-temperature exhaust?
Yes, we offer high-temperature media options (e.g., fiberglass with PTFE coating) capable of operating up to 150°C. Please specify your temperature requirements when ordering. -
How do I determine the correct size for my spray booth?
We recommend measuring the filter housing dimensions (width, height, and depth) and the number of bag pockets required. Our engineers can also provide CAD drawings if you send us your housing specifications. -
Are these filter bags washable or reusable?
Standard coarse filter bags are typically disposable. However, we can manufacture washable versions using durable synthetic media (e.g., polyester felt) upon request. Please note that washable filters may have slightly different pressure drop characteristics. -
What is the typical lead time?
For standard sizes, production takes 10–15 working days. Custom orders may require 15–25 working days, depending on complexity and quantity. We offer expedited shipping for urgent needs. -
Do you provide samples before bulk order?
Yes, we can provide sample bags (small quantity, charged) for testing. The sample fee is refundable upon bulk order placement. Contact our sales team to arrange. -
Can the PLC core be retrofitted into existing filter housings?
In many cases, yes. We can design a core that fits your existing header plate and bag arrangement. Please provide detailed drawings or photos of your current system for evaluation. -
What certifications do your products have?
Our manufacturing processes follow ISO 9001 quality management system (available upon request). Specific product certifications can be arranged based on customer requirements and destination market regulations.
