Mini Pleat HEPA Filter #82-4311 for Pro Spot Fume Extractor.

Product Overview

The Pro Spot Mini Pleat HEPA Filter (SKU: 82-4311) is the primary, high-efficiency particulate filtration component for Pro Spot's portable fume extraction systems. Engineered to protect technicians in heavy-duty collision repair and fabrication environments, this filter safely captures hazardous welding smoke, metallic dust, and microscopic airborne contaminants before they can enter the operator's breathing zone.

Designed with an advanced "mini-pleat" architecture, the filter maximizes the internal surface area without restricting the extractor's pneumatic suction power. This allows it to reliably trap 99.97% of airborne particulates as small as 0.3 microns, including dangerous elements like hexavalent chromium and zinc oxide. When used in conjunction with the Carbon Pre-Filter (82-4312), the HEPA filter's lifespan is significantly extended, ensuring your shop remains compliant with occupational safety standards while keeping consumable costs manageable.

Key Features

• True HEPA Filtration: Certified to capture 99.97% of microscopic particulates down to 0.3 microns, providing hospital-grade air filtration for industrial welding environments.

• Mini-Pleat Design: The high-density pleated construction drastically increases the total filtration surface area within a compact frame, extending the filter's operational lifespan and maintaining consistent airflow.

• Hazardous Fume Capture: Specifically designed to trap dangerous automotive welding byproducts, including aluminum dust, manganese, and hexavalent chromium (produced when welding stainless steel).

• OSHA Compliance: Helps collision centers and fabrication shops meet strict occupational safety regulations regarding indoor air quality and mandatory source-capture fume extraction.

• Direct OEM Replacement: Manufactured by Pro Spot to guarantee an airtight seal inside the extraction unit, preventing hazardous bypass leaks that can occur with aftermarket alternatives.

Technical Specifications

Ideal Use Cases & Applications

• MIG/TIG Welding Stations: The essential primary filter for extracting heavy smoke and metallic particulates during extended steel and aluminum welding sessions in collision repair bays.

• Metal Grinding & Fabrication: Highly effective at pulling airborne metallic dust out of the environment when technicians are grinding down spot welds or shaping custom sheet metal.

• Compliance-Driven Shops: A necessity for commercial auto body facilities looking to maintain a clean, safe work environment and comply with local and federal air quality regulations.

Common Questions (FAQs)

Q: Can I clean and reuse this HEPA filter?
A: No. You should never attempt to blow out a HEPA filter with compressed air. The intense pressure will tear the microscopic fibreglass matrix that traps the particles, completely ruining the filter's efficiency and blowing hazardous dust back into your shop. Once saturated, it must be replaced.

Q: How often does this filter need to be replaced?
A: The lifespan depends entirely on your shop's welding volume. However, the best way to extend the life of this expensive HEPA filter is to regularly change the cheaper Carbon Pre-Filter (82-4312), which absorbs the heavy smoke and large particulates before they can reach and clog the HEPA media.

Q: How do I know when the filter is full?
A: Most Pro Spot fume extractors feature a pressure gauge or an indicator light. When the filter becomes saturated, the machine has to work much harder to pull air through the clogged pleats, causing a noticeable drop in suction power at the torch or hood.
