Introducción del producto

This square unit combines a brushless fan, inlet prefilter and downstream HEPA element in a compact stainless assembly. The 400 mm mounting footprint suits narrow equipment tops; an external terminal box requires additional rear clearance. A local speed control adjusts delivery as the enclosure airflow path is balanced.

Características clave

Compact mounting envelope

The small casing leaves more space around the module for machine brackets and service access.

Protected final filter

An inlet prefilter intercepts coarse particles before air reaches the fan and final filtration stage.

Accessible operating controls

The switch and speed adjustment support local setup without a separate building-wide controller.

Applications

Suitable for small optical inspection housings, electronics handling stations and local clean-air covers. The enclosure must provide an unobstructed return-air route; this supply module does not provide hazardous-material containment.

Customer Product Concerns and Solutions

A standard ceiling module is too large for the machine roof.Use the 400 mm casing to fit the available mounting area, allowing clearance for the electrical connection and inlet.

A concentrated air stream disturbs lightweight parts.Set the fan speed to suit the actual work zone and check the airflow with the enclosure and fixtures in place.

Opciones disponibles

Discuss the mounting seal, supply-voltage configuration and final-filter selection for the intended enclosure. Alternative electrical configurations require matching components.
