APPLICATION
The VENTS TT and VENTS TT PRO fans are featured with wide capabilities and high performance of axial and centrifugal fans and are specifically designed for supply and exhaust ventilation of premises requiring high pressure, powerful air flow and low noise level.
The fans are compatible with round air ducts from Ø 100 to 315 mm. Exhaust ventilation systems based on the VENTS TT fans are the best solution for ventilation of bathrooms and kitchens and other humid premises as well for ventilation of flats, cottages, shops, cafes, etc.
 
DESIGN
The casing is made of high-quality durable plastic.
All the models may be equipped with a regulated timer with turn-off delay adjustable from 2 to 30 min.
The removable impeller and motor block with a terminal box is fixed to the casing assembled with the spigots by means of special clamps with latches. This makes the fan maintenance fast and easy. The fan maintenance does not require total disassembling. Just pull out the central block from the casing and perform required servicing.
 
TT PRO DESIGN FEATURES
The VENTS TT PRO fan casing is made of low flammable polypropylene.
The inlet spigot is equipped with a collector to enable smooth air inlet to the fan.
The hemispheric impeller shape and specially profiled blades increase the air flow circular velocity and provide higher pressure and capacity as compared to standard axial fans.
The diffuser, the specially profiled impeller and the directing vanes at outlet from the fan casing distribute air flow in such a way as to attain the best combination of high performance, enhanced pressure and low noise.
 
MOTOR
The models of VENTS TT series are equipped with a single phase motor and are available in single or two speed modifications. Some dimension types are available with a more powerful motor (VENTS TT…S).
The models of VENTS TT PRO series are equipped with single phased double-speed motors with low energy demand.
The motors have thermal overheating protection to prevent the motor overload.
The ball bearings extend the motor service life up to 40 000 hrs. at non-stop operation.
The motor has IP X4 ingress protection rating.
 
SPEED CONTROL
The double-speed motors are controlled with a built-in switch (V option) or an external switch for multi-speed fans (available upon separate order).
An integrated speed controller (option P), an external TRIAC or autotransformer speed controller (available upon separate order) are used for smooth speed control when connected to the maximum speed terminal.
 
MOUNTING
The fans are suitable for mounting at any angle and point of the system. Several fans may be installed inside one system.
Several fans may be installed inside one system:
parallel mounting to increase air flow;
in series mounting to increase operating pressure;
The fan case is equipped with a flat mounting plate to attach the fan to the wall.
The mounting box may be installed in any position to facilitate mounting and wiring.
