GRILLES & DIFFUSERS

Linear Slot Diffuser.jpg
  • Versatile supply linear diffuser for wall, ceiling or sill installation.
  • Available in two slot widths, 19mm, 25mm.
  • Available in single piece lengths from 300mm to 2500mm.

Linear Slot Diffusers manufactured by KMC have been designed to satisfy architectural concepts that require continuous length applications without compromising air distribution performance.

These diffusers utilizes an adjustable vane in each slot to control the direction of air discharge either parallel with or perpendicular to its face surface.

Jet Diffuser.jpg
  • Core consists of 4 stamped, curved blade deflectors that are neck mounted and off the face to help mask appearance from the room.
  • Field configurable 1, 2, 3, or 4 way blow patterns without changes in sound or pressure

KMC perforated diffusers have been designed to provide superior performance characteristic with application flexibility.

These diffusers provide horizontal air pattern with a strong coanda effect against the ceiling. Louvered air pattern controllers located at the inlet neck of the diffuser provide positive air flow control.

Spot Diffuser.jpg
  • Small nozzle sizes provide shorter throws for smaller spaces.
  • Field adjustable directional control up to 75° total angle.
  • Eyeball assembly smoothly rotates in fixed mounting flange – seals prevent leakage.

KMC Spot diffusers are recommended for use in large spaces such as malls , exhibit hall etc., Where directional control of conditioned air is of very much important.
The adjustable nozzle models make it possible to adapt the jet discharge angle to suit differing operating conditions.

DISC VALVES.jpg
  • This disc valves consist of the valve ring and central disc.
  • The air volume flow rate is adjusted by rotating the central disc which alters the size of the gap.

KMC Supply and Exhaust disc valves are utilized where the control of supply or Exhaust air volume flow rate is the primary consideration.

These valves offer considerable cost advantage over conventional grilles and diffusers without Compromising performance or aesthetics.

CIRCULAR DIFFUSER.jpg
  • Expanding cone design provides excellent horizontal air discharge preventing drafts in the occupied zone.
  • 360° air pattern delivery maintains horizontal pattern with or without ceiling effect.

KMC Circular Diffusers have a circular cone with elegant styling to provide maximum air diffusion efficiency.

Perforated Diffuser.jpg
  • Core consists of 4 stamped, curved blade deflectors that are neck mounted and off the face to help mask appearance from the room

  • Field configurable 1, 2, 3, or 4 way blow patterns without changes in sound or pressure

  • Removable perforated face uses concealed spring clips

KMC perforated diffusers have been designed to provide superior performance characteristic with application flexibility.

These diffusers provide horizontal air pattern with a strong coanda effect against the ceiling. Louvered air pattern controllers located at the inlet neck of the diffuser provide positive air flow control.

LINEAR BAR GRILLES.jpg
  • Airline models include 6mm wide bars on 12mm centres (Model LBG).
  • Core deflection angles of 0°, 15°, or 45° for precise directional control of supply air or return air use.
  • Lengths to 2500mm for full sections.
  • Heights from 50mm to 450mm (with removable core).

KMC Linear Bar Grilles are designed to have combined benefits of architectural beauty with performance versatility. These Grilles are an excellent choice for applications where they are exposed and accessible to heavy traffic.

SINGLE DEFLECTION GRILLES.jpg
  • Single set of horizontal or vertical blades.
  • 19mm spacing of individually adjustable blades.
  • Maximum size one piece construction is 1200mm x 1200mm.

KMC supply Grilles and Registers usually have adjustable louvers and are available in single or double deflection models.
The Single deflection grilles are designed to have one set of blades in the horizontal or vertical orientation.

DOUBLE DEFLECTION GRILLES.jpg
  • Front blades selected as horizontal or vertical for visual effect
  • 19mm spacing of individually adjustable blades rotates smoothly without bending
  • Maximum size one piece construction is 1200mm x 1200mm

KMC supply Grilles and Registers usually have adjustable louvres and are available in single or double deflection models.

The Double deflection grilles are designed to have two sets of blades in both the horizontal or vertical orientation with air pattern being adjustable in both horizontal and vertical planes.

EXHAUST GRILLES .jpg
  • Blades selected as horizontal or vertical for visual effect.
  • 19mm blade spacing
  • Maximum size one piece construction is 1200mm x 1200mm

KMC Return / Exhaust Grilles utilize core of parallel fixed blades set at a deflection, generally 45° from horizontal to provide minimum “see through”.

These Grilles are mostly utilized for side wall application with blade deflection upward in high applications and down in lower application.

Return Grilles.jpg
  • 12.7mm x 12.7mm x 12.7mm aluminium core.
  • Registers include a factory attached, opposed blade volume control damper.
  • Maximum size one piece construction is 1200mm x 1200mm.

KMC Return / Exhaust Grilles utilize core of cubical grid and mostly used where maximum free area is desired and “see through” is not a concern.

These Grilles are typically used in ceiling applications where “see through” sight lines are minimized to directly below the grille

Door Grilles.jpg
  • The horizontal V shape vanes are not adjustable and are sight proof.
  • The Grille can be either mounted to the wall or the door.
  • Vertical direction is adjustable from 0° to ±30°

KMC air transfer Grilles or Door grilles are typically used in doors and partitions to allow air flow to a space that is not directly served by a ducted source of supply air or a ducted outlet for return or exhaust air.

These Door / Wall Grilles offers the largest free area possible with a completely sight proof or light proof core.
