CRKA 630 T4/T8 5,5/1,1kW

ROOF FAN WITH FOLDING SYSTEM AND ALUMINIUM COWL

MANUFACTURING FEATURES:

  • Protection cowl made of anticorrosive treated aluminum easily removable for motor and impeller maintenance thanks to the integrated folding system.
  • The design of the cowl with a rounded shape is specific to minimize the risk of water ingress due to rain.
  • Equipped with a hinged system to open the motor-impeller set. This system allows easy maintenance and cleaning of the set without the need to disassemble the entire structure. The opening is possible in 2 inclinations: approximately 45º and 90º, as required by the intervention.
  • Structure in anticorrosive galvanized steel and support frame for adaptation to the roof with anti-bird protection grid.
  • High-performance, backward-curved blade (reaction) impellers designed to work without scroll. Self-cleaning system, built in galvanized steel treated with anti-corrosion.
  • Standard asynchronous squirrel cage motor with IP-55 protection and Class F insulation. Standard voltages of 230V50Hz for single phase motors, 230/400V50Hz & 400/690V 50Hz for three-phase 1 speed motors and 400V50Hz for 2 speed motors.

APPLICATIONS

Designed for deck or roof mounting, they are indicated for:

  • Smoke extraction.
  • Air renewal in all types of buildings and industries.
  • Maximum continuous working temperature: transported air 80ºC, ambient 60ºC to -25ºC in three-phase motors.

UNDER REQUEST

  • Special voltages.
  • Special contruction for moving air at 120ºC

CMP-HUT 800x810
Information
DEPRESSION DAMPER (HORIZONTAL or VERTICAL PLACEMENT)

Depression damper for ascending air flow in the intake. The slats block the passage of air when the fan is stopped while when the fan is running the slats move by depression allowing the passage of air. Robust U-shaped frame. The special holes in the corners allow a connection with common union systems on the market such as a duct working in plenum mode. It maintains the overpressure or depression inside a room with respect to the outside or another adjoining room.

MANUFACTURING FEATURES:

- Galvanized steel frame, U-shaped to install in a duct.

- Aluminum slats.

- Ø12 shafts in galvanized steel.

- Ø12 bronze bushings.

- Suitable for 400°/2h (not certified) and temperatures below zero.

- It can be installed directly to the fan, although the use of the frame (B CMP) is recommended.

- Suitable for speed 18 m/s and with some turbulence.
