Paper Frame Filter Supplier providing spray booth filter supply

Paper Frame Filters in Coating Systems

Functions

• Reduces dust entering the spray area
• Improves coating surface stability
• Lowers particle-related defects

Common Applications

• Air intake filtration for coating production lines
• Pre-dust protection in spray paint rooms
• Primary stage filter media in air filtration boxes

Problems Without Paper Frame Filters

• Large dust particles directly enter mid/high-efficiency filters
• Shortened lifespan of HEPA and bag filters
• Faster increase in system pressure drop
• Higher maintenance and replacement cost

Multi-Stage Industrial Filtration System Setup

• Stage 1: Paper frame pre-filter
• Stage 2: Bag filter
• Stage 3: HEPA filter

Difference Between Paper Frame Filters and Other Filters

Compared with Medium-Efficiency Filters

• Paper frame filter: captures large dust particles
• Medium filter: handles mid-sized contaminants

Compared with HEPA Filters

• Paper frame filter: used for pre-stage protection
• HEPA filter: final-stage fine particle filtration

FAQ

What is the main purpose of a paper frame filter?

It is used in the front stage of air filtration systems to capture large dust particles and reduce the load on downstream filters.

How often should it be replaced?

Replacement depends on dust load and pressure differential conditions, requiring regular inspection.
