Clean fan filter unit

Supplies clean air with a HEPA filter

Clean air is supplied by the fan filter unit built into the HEPA filter.

Newly developed wind speed sensor with heated wire resistor

Prevents the ventilation frequency from dropping

Equipped with a newly developed wind speed sensor with heated wire resistor. The sensor detects the wind speed loss due to clogging of the filter to prevent the ventilation frequency from dropping following a drop in the wind speed.

Clogging diagnosis function

Prevents a drop in the wind speed caused by clogging of the filter

When the wind speed drops due to clogging of the filter etc., an alarm will be lit automatically and an external warning can also be output. A variable trimmer to set the threshold for the wind speed level is also fitted as a standard option.

Variable wind speed control function （05FFU）

Allows the wind speed to be raised when it drops

The air flow of the ventilation fan motor built into the fan filter unit can be adjusted by varying the volume. Fine adjustments can be made to the air flow or the air flow can be increased when it drops due to a pressure loss.

Quick top maintenance type with a one touch lock (01FFU - 05FFU)

Easy replacement with the need for tools

A one touch lock is employed to allow the HEPA filter to be replaced easily. HEPA filter can be removed and replaced without the need for tools.

Side suction （A11FFU～A17FFU）

Minimizes the clearance with the ceiling

By taking in outside air from the side of the fan filter unit, it is possible to keep the clearance with the ceiling to a minimum. This is useful when the ceiling of the clean booth installation location is low, or when the height and dimensions of the clean booth body are large.

Bottom maintenance type （A11FFU～A17FFU）

Maintenance at a height can be avoided

HEPA filter can be replaced from inside the booth. Maintenance at a height can be avoided.

A clean environment can be constructed easily

The temperature and humidity can also be controlled by combining it with a precision air conditioner (TCU/ECU)

A clean environment can be built easily by combining the precision air conditioner (TCU/ECU) with a fan filter unit. By passing the precision air produced by the PAU unit through the HEPA filter, clean air with a high level of cleanliness can be supplied locally. Moreover, “temperature and humidity control” and an “optimal clean environment” can be achieved easily as you can select a clean unit according to the volume of the target space and the level of cleanliness required.
