Product Introduction

A cleanroom air handling unit conditions the large, stable airflow needed to control temperature, humidity, pressure cascade and particle transport. The casing uses flush cleanable inner panels, sealed access doors, drainable coil sections and corrosion-resistant hardware. Prefilters protect the coil and downstream final filters, while direct-drive fans modulate against filter loading and room-pressure demand. Coil face velocity, condensate drainage and access clearances are selected to prevent water carryover into downstream sections.

Key Features

Flush internal surfaces reduce exposed ledges around filters, coils and service doors.

Separated prefilter and fine-filter stages protect coils and extend the useful life of downstream final filters.

Sloped stainless-steel drain pans remove condensate from cooling-coil sections without standing water.

Variable-speed direct-drive fans maintain scheduled airflow as filters load and operating modes change.

Customer Product Concerns

Particle control depends on the entire supply-air path remaining clean, dry and pressure-stable through changing filter and thermal loads.

Dust accumulates on internal ledges that are difficult to reach during sanitation.Flush inner panels and removable components leave broad surfaces accessible for wipe-down.

Cooling-coil condensate remains in the unit and supports odor or microbial growth.A sloped stainless drain pan and correctly trapped drain evacuate water from the wet section.

Rising filter resistance reduces room air changes and destabilizes pressure.Fan-speed control responds to airflow or static-pressure feedback across the operating filter range.

Air bypasses the final filter because the holding frame is not uniformly sealed.Gasketed filter tracks apply even compression around each selected filter module.
