Floor Swirl – Horizontal

Price RFDD

Price RFDD floor displacement diffusers are ideal for use where low induction, horizontal discharge, floor level flow is required.

Displacement airflow
RFDD floor displacement diffusers are ideal for use where low induction floor level flow is required. The diffuser slots discharge air in a displacement manner, horizontally across the floor, where it is drawn to heat loads and transports heat and contaminants up to the return grilles in the ceiling.

Floor location
Floor mounted with supply air from below, either duct connected or using a floor plenum chamber.

Dependent throw
Variable throw across the air volume range.

Fixed airflow direction
Non adjustable discharge pattern.

Manual adjustment
Air volume adjustment via basket system. Circular face shape: 200mm diameter.

Radial face pattern
Radial blade style face pattern.

Plastic face
Fire rated engineered polymer (RFDD) meets NFPA90A requirements. Finish Dusty Grey or Black.

Price RFDD floor displacement diffusers are ideal for use where low induction, horizontal discharge, floor level flow is required. The diffuser slots discharge air in a displacement manner, horizontally across the floor, where it is drawn to heat loads and transports heat and contaminants up to the return grilles in the ceiling.

These diffusers create a horizontal flow using narrow slots arranged in a star pattern with a perforated section in the center to resist induction of room air. This generates a low turbulence flow with low velocities to minimize draft when located near seated occupants. This low level discharge is ideal for supplying cool air across the floor of the room and allowing it to rise as the heat load from people and electrical equipment is absorbed. The 8″ (200 mm) diameter diffusers can be placed within 24″ (610 mm) of a seated occupant while maintaining a draft rate of less than 10% according to ASHRAE 55-2004.

  • Fire rated engineered polymer (RFDD) meets NFPA90A requirements
  • Optional variable air volume basket (DBV) for non-ducted VAV applications
  • Core is ready for installation in stepped bore installation. Optional ring press fit and ring law allow for insertion in through-bore floor tiles
  • Complete range of accessory baskets, dampers, fasteners, etc.
  • Discharge air volume is adjustable at the diffuser face without removing diffuser from the floor. Minimum airflow is adjustable from 0% to 50% of maximum airflow
  • Diffuser face has positive interlock, reducing the potential for accidental adjustment of diffusers

Electric adjustment
The optional integral control damper modulates from fully open to fully closed automatically, driven from a 24 VAC actuator mounted underneath the basket
