MODEL TAR TUBE AXIAL R SERIES



Sigrist Design range of inline axial fans offer a means of exhausting air where an inline fan is required. There are seven fan sizes available ranging from 200 mm to 500 mm.
We have developed our units with a galvanised steel casing which can be supplied in a powder coated finish

NOISE LEVELS
The noise level figures have been obtained according to BS-848 Part 2 .The figures given correspond to Sound Power Levels in dB(A) and are measured at 3 meters.

IMPELLERS
The exclusive design of the impellers allows the maximum aerodynamic characteristics combined with a low noise level. They are manufactured in steel, rivited to the rotor and dynamically balanced. The finish is black polyester powdercoat.

ELECTRIC MOTORS
The motors are of induction ,asynchronous type ,with die cast in Aluminium external rotor .
The fans can be supplied with motors of 2 or 4 poles depending on the model.
The ball bearings are totally enclosed and greased for life ,thus enabling a very low noise level and continuous operation. The insulation is Class "B". The Degree of protection is IP44.
The working temperature range is from -40 deg.C up to 60 deg. C.
Thermal protection
All the single phase motors are fitted with a thermal protection device of the self-resetting type ,to protect the motor from dangerous overheating.
All motors incorporate sealed for live ball bearings and are suitable for 240 volt single phase supply.
