Accordion Filters

Technical Specifications:

The Accordion captures liquid overspray through impaction by the process of inertial separation and filters through secondary straining in the Poly-Back.  

  • Recommended Air Velocity:  49-197 fpm, subject to spray operation
  • Recommended Max Pressure Drop:  0.5 – >1 inch w.c., subject to fan motor
Quantities 1-9 boxes: freight not included.  A 10% freight discount is applied in cart.
Quantities 10+ boxes:  SHIP FREE!

Unlike fiberglass, polyester, and paper mesh filters, The Accordion loads overspray particles from the back, eliminating uneven airflow caused by particles face-loading on the front of the filter directly behind the point of spray.  The accordion design separates the overspray particles from the airflow through the force of inertia and captures them deep inside holding pockets, eliminating particle migration.  As a result, The Accordion can last 3-5x longer than other filter media.

The Accordion Standard

SINGLE STAGE FILTRATION

The Accordion Standard is the better baffle to arrest tacky, slow-to-dry, overspray such as high solid enamels, epoxy, asphalt, and varnish.  This single-stage media tests at 98.3% paint arrestance efficiency and holds > 6 lbs of overspray per 20×20″ pad.
