The new TTI fan is incorporated into a specially designed sound-insulated casing that provides silent fan operation combined with high aerodynamic properties.
Available dimension sizes include 200, 250 and 315 mm and the maximum air capacity reaches 2350 m3/h.
The VENTS TTI fans combine wide capabilities and outstanding technical parameters of axial and centrifugal fans to produce powerful air stream and high pressure.
The fans are used in air handling systems installed in commercial and industrial premises requiring low noise level, including libraries, conference halls, education facilities, kindergartens, etc.).
Casing
- inner casing is made of polymer coated steel;
- internally perforated casing let sound waves come through and be directed to a layer of sound-insulating material at some angle;
- 50 mm heat- and sound-insulating layer made of isover in the casing;
- specially designed perforated casing and sound absorbing material take care of sound attenuation in a broad frequency band;
- the inner casing and the impeller are made of high-quality durable plastic: ABS (Ø 200, 250 mm) or low flammability polypropylene (Ø 315 mm);
- easily detachable motor and impeller block facilitates servicing and maintenance operations;
- power is supplied to the fan though the external airtight terminal box on the fan casing;
- the fan connecting pipes are rubber sealed for airtight connection to the air ducts.
Motor
- single-phase double speed motor or roll bearings with service life up to 40 000 hours;
- motor overload protection with thermal switches;
- IPX4 ingress protection rating.
Control
- double speed motor step control with an external speed switch (available upon separate order);
- TTI…V models are equipped with an integrated speed switch;
- TTI…T models are equipped with a regulated timer adjustable between 2 and 30 minutes;
- smooth or step speed control with a triac or transformer speed controller connected to the high speed terminal.
Mounting
- any mounting place within the ductwork system;
- fan mounting at any angle;
- several fans may be installed in parallel to attain higher air capacity or in series to increase operating pressure in the system;
- fan casing is equipped with mounting brackets for attaching to the wall.
