Design
1. The casing and the impeller are made of high-quality durable ABS plastic, UV resistant.
2. The intellectual impeller design makes the fan efficiency high and the service life long.
3. Protection rating IP X4.
Mounting
1. The fan is mounted into a matching duct size. Fastening with clamps in case of flexible duct connection.
2. The mounting bracket enables fan installation on both horizontal and vertical flat surfaces (VKO1k model).
3. Two fans can be installed in series for higher performance.
4. For 12 V low-voltage motor fan connection to 220 V / 50 Hz power mains use the step-down transformer TRF 220/12-25 that is available upon separate order.
Motor
1. Reliable and low-watt electric motor.
2. Designed for continuous operation and requires no maintenance.
3. Equipped with overheating protection.
Speed Control
Manual:
1. The fan is controlled by a room light switch. It is not included in the delivery set.
2. The fan is controlled by the built-in pull cord switch V. Not applied in case of ceiling mounting.
3. Speed control is possible through a thyristor speed controller (see Electrical Accessories). Several fans may be connected to the same controller. Speed controllers can not be connected to the fans with Т, ТН, ТР, VТ, VТН modifications.
Automatic:
1. By the electronic control unit BU-1-60 (see Electrical Accessories). The control unit is supplied separately.
2. By the timer T (the built-in run-out timer enables the fan operation within 2 to 30 minutes after the fan switching off).
Operation Logic
Operation modes for T modifications of VENTS Quiet line 100, 125, 150 and VENTS Quiet line 150 Extra models are selected by setting the DIP switch in required position.
Mode 1
The fan is turned off by default. The fan starts operating at the low speed when the switch is closed.
Mode 2
The fan is turned off by default. The fan starts operating at the high speed when the switch is closed.
Mode 3 (two-speed mode)
The fan operates at the low speed by default. The fan switches to the high speed when the switch is closed.
Mode 4 (Automatic interval mode)
The fan operates at the low speed by default. The fan switches to the high speed each set time period (adjustable from 1 to 15 hours) and operates up to 30 min to ventilate the premise with maximum capacity. After that the fan models back to the continuous operation at low speed.
