Introduction de produit

This floor-standing fan filter unit combines a fan-and-filter cabinet with a coated steel support frame. The cabinet is held above floor level, with a perforated guard in front of the filter and a separate fan chamber behind it. Leveling feet support the assembly at its installed location. The freestanding format provides a horizontal air source alongside a bench or machine without using a suspended ceiling grid to carry the unit.

Key Features

The support frame carries the cabinet independently of the room ceiling.

An open discharge face can be positioned beside equipment that cannot fit inside a small enclosed bench.

The floor-supported layout keeps the overhead service space available for other utilities.

The exposed front guard and surrounding frame remain accessible for routine surface cleaning.

Des solutions pour votre application

A fixed horizontal air source is most useful when its location follows the work rather than the ceiling layout.

A local assembly step sits outside the available ceiling-filter positions.Place a floor-supported module beside that step and evaluate the air path over the exposed component.

A conveyor and its service doors leave little freedom for a standard workstation.Plan the frame footprint and discharge elevation around the moving equipment and access envelope.

A small change in outlet alignment leaves part of the handling area outside the stream.Set the leveling feet and record the final position so the same geometry can be restored after maintenance.

Airflow reaching the process differs from the reading at the filter face.Assess the required work locations with normal tools, obstructions and room air currents present.

Choose these construction details with the supplied unit. A reverse-flow extraction configuration is a different airflow function, not an automatic feature of this positive-supply module.

Selection and Installation

Set the working envelope

Describe the exposed component, bench height, conveyor opening and handling direction. Measure the available floor footprint as well as the distance from the outlet to the operation. A larger discharge face does not automatically extend the useful clean-air zone by the same proportion.

Place the unit around the process

Keep the fan intake clear and arrange the workstation so hands, tools and large components do not block the air path upstream of the sensitive surface. Nearby doors, extraction points and supply diffusers can disturb the horizontal stream. Check airflow with the actual equipment and operator positions in place.

Compare the supplied operating configuration

Select the final-filter grade, fan and control arrangement together. Obtain delivered air volume, face-velocity distribution, available static pressure, electrical input and sound data at the same specified operating condition. Frame dimensions, weight, electrical supply and filter-removal clearance also belong in the purchase specification.

Choose fixed or movable support

Use the floor-standing version when the outlet normally serves one location. If the source must move between workstations, compare the mobile fan filter unit and its handling requirements. Secure and level the installed frame without obstructing cleaning access. This open supply arrangement does not provide hazardous-material containment or establish an ISO room classification.
