STjh large 1175 mm square equipment FFU with twin EC fan grilles and reinforced full filter face

STJH-EQUIPMENT-FAN-FILTER-UNIT-4X4

Equipment Fan Filter Unit 4 × 4 ft

A large square EFU for broad tool-top clean-air zones and process enclosures.

1175 mm square footprint
0.3-0.5 m/s air speed
275 Pa static pressure

Introduction de produit

The 4 x 4 EFU expands to a 1175 x 1175 mm square footprint with a 160 + 35 mm cabinet height. It operates across a cited 0.3-0.5 m/s air-speed range, provides 275 Pa static pressure and uses 100-175 W. Its equal-sided geometry suits large square process enclosures that need broad localized coverage rather than the narrow pressure-priority layout of the 2 x 4 unit.

Key Features

Broad square coverage

Equal 1175 mm sides distribute filtered air over large square tools and work zones.

Defined velocity range

The 0.3-0.5 m/s duty supports balancing for different process openings.

Intermediate pressure capability

A 275 Pa static value balances broad face area with equipment resistance.

Applications

Suitable for large process enclosures, square tool roofs and localized mini-environments. The equipment structure and return path must support the wider airflow face and selected operating velocity.

Solutions for Your Application

A narrow EFU cannot cover a square process chamber evenly.Use the 1175 mm square footprint and balance within the stated velocity range.

The larger module can load the equipment roof unevenly.Support the full perimeter and coordinate lifting and maintenance access before installation.

Options disponibles

Select the final filter, fan control, electrical package and sealing interface for the tool. Confirm the required velocity and structural support.
