BLOX™ patented dry scrubber filter systems replace fragile cardboard box filters with engineered reusable housings. No fiber contamination, dramatic waste reduction, and flat-pack assembly that saves hours per trolley.
The engineered alternative to cardboard box filters in Dürr® EcoDry X trolley applications.
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.
BLOX™ uses 100% recycled non-fibrous corrugate for the filter housing. No fiber particles are introduced to the air, protecting finish quality.
Housings arrive folded flat. A simple press forms them into a cube that slides into the trolley. Saves hours of labor per trolley.
Tested to withstand well over maximum airflow without failing, keeping internal components cleaner for easier change-outs.
Used with Walk Industrial's reusable patented Grid Guard® system, change-outs of the BLOX™ system are quicker and easier than any other filter.
Designed and manufactured by Walk Industrial with the same engineering quality behind the patented BowTie® filter platform.

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.

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.
