Why Facilities Are Switching to BLOX™

The engineered alternative to cardboard box filters in Dürr® EcoDry X trolley applications.

Reusable Housings

With most coatings, only the patented BowTie® filter inserts need to be swapped — the BLOX™ housings stay in place, saving hours of cleanup per trolley per shift.

🛡

No Fiber Contamination

BLOX™ uses 100% recycled non-fibrous corrugate for the filter housing. No fiber particles are introduced to the air, protecting finish quality.

📦

Flat-Pack Assembly

Housings arrive folded flat. A simple press forms them into a cube that slides into the trolley. Saves hours of labor per trolley.

💪

Engineered to Hold

Tested to withstand well over maximum airflow without failing, keeping internal components cleaner for easier change-outs.

Works with Grid Guard®

Used with Walk Industrial's reusable patented Grid Guard® system, change-outs of the BLOX™ system are quicker and easier than any other filter.

🇺🇸

Made in the USA

Designed and manufactured by Walk Industrial with the same engineering quality behind the patented BowTie® filter platform.

BLOX Filter System housing for Dürr EcoDry X trolley

How BLOX™ Works

The BLOX™ system separates the filter housing from the filter media. The 100% recycled non-fibrous corrugate housing forms the structural container that slides into the Dürr® trolley.

Inside, patented BowTie® filter inserts handle the actual overspray capture. When filters load up, only the BowTie® inserts need to be replaced — the BLOX™ housing stays in place with most coating types.

  • Internationally patented dry scrubber system
  • Reusable housings with most coatings
  • No fiber particle contamination
  • Flat-pack assembly saves hours per trolley
  • Dramatically less waste than cardboard

BLOX™ vs. Cardboard Box Filters

Side-by-side on what actually happens in Dürr® EcoDry X trolley applications.

Cardboard Box Filters

  • Fiber particles contaminate the air and affect finish
  • Prone to blowouts that coat booth internals with overspray
  • Single-use — entire unit disposed every cycle
  • Must be built on-site or stored pre-assembled
  • Enormous disposal volume and cost
VS

BLOX™ Filter System

  • 100% recycled non-fibrous corrugate — zero fiber contamination
  • Tested beyond maximum airflow without failure
  • Reusable housings — only swap the BowTie® inserts
  • Flat-pack assembly, slide-in inserts
  • Dramatically reduced waste and disposal cost

BowTie® Inside Every BLOX™ System

The BLOX™ housing is only half the system. Inside every unit, patented BowTie® filter inserts do the actual overspray capture — the same internationally patented pocket filter technology trusted by Tier 1 automotive facilities and independent shops worldwide.

BowTie® filters last up to 22× longer than conventional pad filters, which means fewer insert swaps per trolley, less waste, and more production uptime across your Dürr® EcoDry X fleet.
