상품 소개

The makeup air unit delivers conditioned outside air in proportion to fume-hood, process, canopy or room exhaust. Unlike a general fresh-air unit, its primary control duty is mass-balance: supply airflow must respond predictably as exhaust devices start, stop or modulate. Filters, coils and optional humidity treatment bring the outdoor air to a condition that the room or recirculation system can accept without upsetting temperature and moisture control. A low-leakage casing and fast fan response help prevent door forces and unwanted infiltration.

주요 기능

Supply airflow can track a combined exhaust-air signal rather than operate at one fixed ventilation rate.

Tempering coils prevent replacement air from imposing abrupt heating, cooling or moisture loads on the cleanroom.

Fast variable-speed fan control supports stable room pressure during process exhaust transitions.

Separate intake filtration prevents outdoor particles from entering through uncontrolled building leakage paths.

응용 프로그램 솔루션

A facility can have sufficient cooling capacity yet still lose pressure control when exhaust and replacement air do not change together.

Starting a process exhaust fan pulls adjacent cleanrooms below their pressure setpoint.The makeup fan follows the combined exhaust airflow signal with a configured offset for pressure cascade.

Untempered winter replacement air causes cold drafts and local condensation.Preheat and final heating stages deliver supply air at a controlled temperature.

Outdoor humidity overwhelms the room AHU during high exhaust operation.Cooling and dehumidification are sized for the full makeup-air latent load.

Unfiltered infiltration enters around doors when replacement air is insufficient.Measured makeup volume enters through staged filters and a defined supply path.
