Введение продукции

The high-airflow fan filter unit combines two EC blowers with a broad final-filter face in a reinforced ceiling housing. A central enclosure serves the twin-fan assembly, and the wide filter frame provides the outlet area for clean-air distribution. The large-format arrangement is intended for clean-air zones in which total delivered volume and the spatial distribution of that air must be considered together.

Основные характеристики

Two EC blowers are incorporated into a single large-format ceiling module.

The final-filter face extends beneath both blower positions.

A central enclosure brings the two blower connections together above the outlet assembly.

A reinforced perimeter supports the wide filter and diffuser assembly.

Решения для вашего приложения

A high total airflow figure is only useful when the outlet pattern, control zoning and service requirements suit the work area.

One large module and several smaller modules create different control and maintenance layouts.Compare independent zones, electrical connections, ceiling coverage and replacement access before choosing the footprint.

A total volume figure does not show whether air reaches the far edges of a wide outlet.Define a multi-point velocity check across the effective filter face, including the areas beneath each blower.

A wide filter assembly needs space for removal as well as installation.Allow a clear service route and a safe lifting method for the complete filter and diffuser assembly.

Equal motor speeds do not by themselves establish equal airflow from the two fan zones.Evaluate the installed outlet pattern and use the specified control adjustment method when balancing the module.

Air-Volume Selection and Installation

Size by delivered volume and usable outlet area

State the required total airflow in m³/h, the external resistance and the final-filter configuration. Use the effective open filter face when relating volume to average velocity; nominal housing area is not the same as usable outlet area. Room air-change calculations also require the room volume and the complete supply-and-return layout.

Choose the footprint and service arrangement

Provide the ceiling opening, supporting grid, available headroom and the route for lifting and replacing the filter assembly. Select the filter grade and sealing arrangement with the unit. Local adjustment and remote control are separate configuration choices; the supplied control system determines how the two blowers are adjusted and monitored.

Balance both fan zones

During commissioning, check total delivery and the velocity pattern at several positions beneath the filter rather than only at the centre. Match the circuit to the supplied electrical rating, secure the wide housing on its specified supports and isolate power before servicing either blower.

For resistance-led selections, compare the high-static-pressure fan filter unit. For smaller independently controlled ceiling zones, review the EC fan filter unit.
