Ceiling Fan Filter Unit

The Ceiling Fan Filter Unit is an FFU specifically intended for modular cleanroom ceiling systems. It can be installed directly into standard ceiling grids or dedicated FFU ceiling frames, allowing the integrated fan and high-efficiency filtration section to supply filtered air downward into the clean area.

Typical module sizes are approximately 1200 × 600 mm, 1200 × 900 mm and 1200 × 1200 mm. Rated airflow ranges from 770 to 2,300 m³/h, while outlet velocity is 0.30–0.50 m/s.

Available filtration grades include H13, H14 and ULPA. Control can be configured for individual speed adjustment or group control.

Actual module dimensions and airflow need to be confirmed according to the ceiling structure and project requirements.

The ceiling-mounted design allows several units to be combined across a cleanroom ceiling. The quantity and arrangement can be selected according to cleanroom grade, room area, air-change requirements and desired coverage.

The supplied information also lists actual FFU module sizes of approximately 1132 × 532 mm and 1132 × 832 mm. These units can be applied in unidirectional or mixed-flow clean environments.

One advantage of a modular Ceiling Fan Filter Unit layout is that the clean-air supply can be adjusted when production requirements change. Units can be added or removed, or their operating airflow can be changed, instead of redesigning the entire centralized air-supply system for every layout adjustment.

Applications include semiconductor plants, electronics workshops, pharmaceutical clean areas and biotechnology facilities.

Jiangsu Renhe has development, equipment design, production and service capabilities in air filtration and clean-air products.

For ceiling FFU projects, the equipment can be matched according to the customer's ceiling-grid dimensions, clean-area size, target filtration grade and control method.

OEM/ODM and manufacturing according to technical drawings are supported. Before production, buyers can confirm external dimensions, installation boundaries, outlet velocity and whether the system will use individual or group control.

This step is particularly important because a Ceiling Fan Filter Unit needs to physically match the ceiling framework. Confirming the module interface in advance can reduce installation adjustments at the project site.

Photos or videos can be supplied during production so project buyers can follow manufacturing progress.

A 100% inspection is completed before packing, and third-party inspection is accepted. For export shipment, cartons with three-plywood pallets or wooden cases can be used according to unit size, with protection for the housing, fan, filtration component and control section.

Projects requiring customized module dimensions can also discuss a sample or prototype before volume production. The listed customized sample-development period is 7 days.
