Paint Booth Filters That Actually Last

The patented BowTie design creates more effective filtration area in the same footprint — capturing more overspray, maintaining airflow longer, and cutting change-outs dramatically.

Engineered to Outperform

Every aspect of the BowTie filter is designed around real production demands — not lab conditions.

Directional Airflow

Engineered airflow paths control how overspray loads into the filter instead of choking a flat face. More surface area, more holding capacity.

Dramatically Fewer Change-Outs

Up to 22× longer life than conventional pad filters in the right applications. Less downtime, less labor, less waste.

Consistent Booth Performance

Stable airflow and predictable pressure drop throughout the filter's life. Better booth balancing and cleaner finishes.

Less Waste

Longer life means fewer filters in the dumpster. Reduced disposal volume and cost for your operation.

More Production Time

Less time changing filters and cleaning stacks means more time painting. The math is simple.

🛡

Cleaner Work Environment

Better capture efficiency keeps overspray out of the air and off surfaces. Healthier for your team.

Built for Real Production

BowTie Filters were created after repeated visits to facilities struggling with frequent change-outs and poor air quality. Walk Industrial spent years testing and refining the design in real-world applications before patenting the result.

Today, BowTie serves everyone from Tier 1 automotive suppliers to independent paint shops.

  • Fewer change-outs per shift
  • More consistent airflow throughout filter life
  • Less waste and stack cleaning
  • Better booth balancing
  • Cleaner work environment

BowTie vs. Conventional Filters

A side-by-side look at what changes when you switch.

Conventional Pad Filters

  • Flat face chokes quickly under heavy overspray
  • Frequent change-outs and production stops
  • Inconsistent airflow as filter loads
  • High waste volume and disposal cost
  • More stack cleaning and maintenance
VS

BowTie Filters

  • Directional airflow uses more filtration area
  • Up to 22× longer life in the right applications
  • Stable pressure drop and booth performance
  • Dramatically less waste per production cycle
  • Cleaner internals and less maintenance

Applications

BowTie filters are built for environments where capture efficiency and holding capacity matter.

Coatings & Adhesives

Varnish, adhesive, and specialty coating applications where holding capacity and capture efficiency are critical.

BowTie filter box for Dürr booth systems

Dürr® Booth Systems

Specialized BowTie® configurations for demanding high-volume Dürr® booth applications, including patented built around BowTie® inserts for the EcoDry X trolley.

BowTie® Inside BLOX™ Filter Systems

If your facility runs Dürr® EcoPaint EcoDry X trolley booths, the patented BowTie® filter is also available as the engine inside BLOX™ Filter Systems — a complete drop-in replacement for cardboard box filters.

BLOX™ uses a 100% recycled non-fibrous corrugate housing that stays in place across most coatings; only the BowTie® inserts get swapped at change-out. The result: same patented filtration performance, dramatically less waste, no fiber contamination, and faster trolley turnover.
