Surface Mount Auto Shutter Fan<br />
VENTS MA Series<br />
ESC CODE:<br />
• V150MA<br />
Axial fans with automatic louvre shutters<br />
for exhaust ventilation with the capacity up<br />
to 345 m 3 hr.<br />
Applications<br />
• Continuous or periodic exhaust ventilation<br />
of bathroom, showers, kitchens and<br />
other utility spaces.<br />
• <strong>Ventilation</strong> shaft mounting or duct connection.<br />
• Low to medium air flow motion for short<br />
distances at low air resistance.<br />
• Compatible with 100mm, 125mm and<br />
150mm air ducts.<br />
Design<br />
• Modern design and aesthetic look.<br />
• The casing and the impeller are made<br />
of high quality durable ABS plastic, UV<br />
resistant.<br />
• The intellectual impeller design makes<br />
the fan efficiancy high and the service life<br />
long.<br />
• Fan is equipped with a thermal actuator<br />
that provides smooth opening and shutting<br />
of automatic louvre shutters for air back<br />
flow prevention.<br />
• Protection rating IP24<br />
Motor<br />
• Reliable and low-watt electric motor.<br />
• Designed for continuous operation and<br />
requires no maintenance.<br />
• Equipped with overheating protection.<br />
Modifications and Options<br />
• MAL - the motor is equipped with ball<br />
bearings for long service life (approx.<br />
40,000hours) and fan mounting at any<br />
angle. The bearings are maintenance free<br />
and contain enough grease for the entire<br />
operating period.<br />
Control Manual:<br />
• The fan is cotrolled by a room light<br />
switch. It is not included in the delivery<br />
package.<br />
• Speed control is possible through a<br />
thyristor speed contoller (see Electrical<br />
Accessories). Several fans may be connected<br />
to the same controller.<br />
Mounting Features<br />
• The fan is mounted directly into the<br />
ventilation shaft.<br />
• Flexible duct application is recommended<br />
in case of remote location of the<br />
ventilation shaft. The air duct is connected<br />
to the fan exhaust flange through a clamp.<br />
• Fixed to wall by self-tapping screws.<br />
• Suitable for ceiling mounting.<br />
• Flange of 92mm length for easy mounting<br />
into concrete walls and floor decks up<br />
to 100mm thick.<br />
