Air Filters and Chemical Filtration
Washable Steel Mesh Air Filter
A rugged permanent pre-filter built from layered steel wire media for high-velocity or abrasive industrial air streams.
- Heavy-Duty Steel Media
- Washable Permanent Design
- High-Velocity Stability
- Galvanized or Stainless Build
Product Introduction
The washable steel mesh air filter combines crimped wire cloth and expanded-steel media inside a rigid galvanized or stainless frame. Compared with an aluminum filter, the steel pack withstands greater handling loads and abrasive debris at high face velocity. Alternating mesh layers create a depth-loading impingement path, while welded or folded face retainers prevent the pack from bulging. Stainless construction is available for wet or chemically aggressive service where galvanized coatings are unsuitable.
Key Features
Expanded-metal face guards resist impact and keep the media pack flat at elevated velocity.
The permanent assembly can be washed and returned to service after complete drying.
Galvanized and stainless constructions let the frame and media match the corrosion environment.
Customer Product Concerns
A steel mesh filter is selected for mechanical durability, but its corrosion grade and cleaning method must fit the actual contamination.
Lightweight mesh panels deform when exposed to debris impact or aggressive handling.Crimped steel media and rigid expanded-metal guards maintain the panel profile under heavier service.
Galvanized surfaces deteriorate in continuously wet or chloride-rich air.An all-stainless frame and media option provides a more suitable corrosion-resistant construction.
Cleaning jets displace loosely packed wire layers and create thin spots.Mechanically compressed media and fixed face retainers hold the layer sequence in place.
Oil-laden dust remains trapped when the filter is rinsed with water alone.Compatible detergent loosens the film before thorough rinsing and complete drain-down.
Typical Applications
Industrial make-up air intakesPaint and process equipment pre-filtrationMachinery cooling-air cabinetsHigh-velocity exhaust or recirculation systemsWet-area ventilation with stainless construction
