STjh 2 by 3 foot explosion-proof ULPA FFU with sealed conduit boxes and twin top service panels

STJH-EXPLOSION-PROOF-FFU-2X3-TOPSIDE

Fan Filter Unit 2 × 3 ft Top-Side Explosion-Proof

An intermediate rectangular hazardous-location FFU for narrow process zones that need more filter area.

2 x 3 ft intermediate footprint
Stainless housing with 304 stainless filter frame
Top-side ULPA service

مقدمة المنتج

This 2 x 3 ft stainless fan filter unit extends the ULPA face beyond the compact square model while remaining narrower than the 2 x 4 ft configuration. It uses top-side filter access, positive-pressure supply and the cited family arrangement of a non-sparking motor in a cast-iron explosion-proof housing. The intermediate footprint is suited to classified process lanes where ceiling width is constrained but a longer clean-air zone is required.

الخصائص الرئيسية

Narrow-zone coverage

The three-foot length follows dispensing or chemical-process lanes without requiring a full 2 x 4 ft module.

Stainless filter interface

A stainless cabinet and 304 stainless filter frame support cleanable construction around the ULPA stage.

Hazardous-location drive basis

The cited family uses a non-sparking motor within a cast-iron explosion-proof enclosure.

Applications

Suitable for narrow hazardous dispensing stations, chemical-processing clean zones and classified work cells requiring a longer filtered ceiling face. The complete electrical, structural and filtration configuration must be matched to the site's classification and process materials.

Solutions for Your Application

The 2 x 2 ft module leaves the ends of a narrow process lane outside the main supply area.Use the three-foot face to extend coverage while preserving a compact two-foot width.

Hazardous-area compliance can be compromised by ordinary field wiring or controls.Coordinate the complete motor enclosure, isolator, cable system and control arrangement with the classified-area design.

الخيارات المتاحة

Define the area classification, 120 or 240 V input, ULPA filter seal, stainless finish, wiring interface and top-side service clearance. Final suitability depends on the assembled installation.
