These ventilation units are quick and easy to assemble, requiring only a simple square cut to be made into the enclosure panel before they can be clicked in, without requiring screws.
The click-in system is suitable for panel thicknesses of between 1.2 and 2.4mm, making it suitable for almost all of the B&R range of enclosures.
A kit is included in the pack for a more traditional installation method should the panel used fall outside of this range.
While the standard direction of air flow on these ventilation units is from the outside to the inside of the enclosure, if required the direction can be reversed by removing and remounting the fan in the opposite direction.
Texa FAN ventilation units have a high volumetric efficiency, with an expected life of 30,000 working hours at an ambient temperature of 55ºC.
They have all been designed to ensure that quick and safe electrical connections can be made via a terminal board.
Maintenance is quick and easy, with ready access to filter cloths and washable filter cloths available if desired.
Featuring a progressive filtering surface made from synthetic fibres, the standard cloth filter supplied with these ventilation units is an EU4 type which has a filtering efficiency equivalent to 91% and an IP44 rating.
A higher rating of IP54 protection is available in the optional extra EU5 filter cloth, which also improves filtering efficiency to 97%.
