Extraction towers

ROOF-CM series

APPLICATIONS

This series is designed for roof mounting, for ducted and direct extraction of air from residential, commercial and industrial buildings such as offices, restaurants, hotels, shopping centres, industrial buildings, plant rooms etc.

RANGE

The series has 7 sizes with impeller diameters from 310 to 710 mm and 4-, 6- and 8-pole motors.

SPECIAL FEATURES

ROOF-CM units have a backward-curved impeller and an outstanding specific fan power that gives excellent flow, high pressure differences and low noise. The specially developed square-section outlet gives the unit a particularly pleasing look that fits easily into any architecture while ensuring proper motor cooling. The steel-wire guard offers less air resistance than the meshes normally used and cleans itself effectively. The electric motor is built to international standards, guaranteeing reliability and robustness as well as easy repair and replacement.

DESIGN

High-efficiency, backward-curved impeller, galvanised
Balanced according to UNI – ISO 1940
Anchoring base with inlet, in weather-protected sheet steel
External steel-mesh guard with weather protection
Cover in engineering plastic
AC electric motor, asynchronous three-phase or single-phase, separated from the conveyed air flow. IP55 protection, class H insulation, S1 duty, built to IEC / EEC / UNEL MEC specifications
Arrangement 5; directly coupled to an overhung impeller
TECHNICAL SPECIFICATIONS (ROOF-CM STANDARD)

NOTE

see the attachments for technical drawings, specifications and accessories of the centrifugal roof units.

DESCRIPTION

Centrifugal roof unit with a backward-curved fan and a rotatable vertical outlet.

APPLICATIONS

The KAMIN centrifugal roof extraction unit is ideal for extracting air from domestic chimneys
with natural draught, thanks to a special design
suitable for operation up to 200 °C. When the fireplace is not in use, it can
be used to ventilate the room and change the air.
DESIGN
High-efficiency, backward-curved impeller in galvanised sheet.
Balanced according to UNI – ISO 1940.
– Anchoring base with inlet and protective mesh in
sheet steel protected against the weather with epoxy polymer.
– Cover in painted aluminium.
– Asynchronous three-phase or single-phase AC electric motor,
separated from the air flow, IP 55 protection, insulation
class H, S1 duty, built to IEC / EEC /
UNEL MEC specifications.
– Version 5; directly coupled to an overhung impeller.
TECHNICAL SPECIFICATIONS
– Conveyed air: max. 200 °C.
– Supply voltage and frequency, single-phase (M) 230 V – 50 Hz
ACCESSORIES
– Speed controllers: SRE-M 1.5 A

Note

while the fireplace is in use, the fan must stay switched on
