Application:
Dwell DMA – Chimney Booster & Inline Exhaust Fan
- Designed to enhance suction in existing chimney systems
- Works efficiently in 6” (150 mm) round ducts
- Best suited where long duct runs reduce chimney performance
- Can be installed in horizontal or vertical duct lines
- Suitable for residential kitchens and light commercial setups
- Reliable ventilation solution for spaces needing high-speed exhaust
Mounting
- The fan is installed inline within the round duct (150 mm diameter).
- Can be mounted horizontally or vertically depending on duct layout.
- Ensure airflow direction matches the arrow marking on the body.
- Secure using duct clamps or proper metal fasteners to avoid vibration.
- Connect to 220V–50Hz power supply (Blue – Live, Red – Neutral as per diagram).
- Electrical installation must comply with local wiring standards.
Compact, powerful, and built for performance — Dwell DMA is the ideal upgrade for improving chimney suction and strengthening duct ventilation systems.

Application
1. Continuous or periodic exhaust ventilation of bathroom, showers, kitchens and other utility spaces.
2. Ventilation shaft mounting or duct connection.
3. Low to medium air flow motion for short distances at low air resistance.
4. Compatible with Ø 100-, 120-, 125- and 150-mm air ducts
Design
1. Modern design and aesthetic look.
2. The casing and the impeller are made of high-quality durable ABS plastic, UV resistant.
3. Various decorative plates for the front panel of the natural aluminum.
4. The intellectual impeller design makes the fan efficiency high and the service lifelong.
5. Protection rating IP34.
Mounting
1. The fan is mounted directly into the ventilation shaft.
2. In case of remote location of the ventilation shaft flexible air ducts may be used. The air duct is connected to the fan exhaust flange through a clamp.
3. Fixed to the wall by means of screws.
4. Suitable for ceiling mounting.
5. To connect a fan with a 12 V low voltage motor to 220 V/50 Hz power mains, it is necessary to purchase a step-down transformer (e.g. the TRF 220/12-25 transformer)
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 BU-1-60 electronic control unit. The control unit is supplied separately.
2. By the T timer (the built-in turn-off delay timer enables the fan operation within 2 to 30 minutes after the fan switching off).
3. By the humidity sensor and the TH timer (if the humidity level in the room exceeds the sensor threshold adjustable value within 60-90 % the fan switches automatically on and operates until the humidity level drops to the standard level, after that the fan continues operating within the time period according to the timer setting, then shuts down).
