Application
The DLK roof roof fans, being easy to install and with a pleasant
and innovative design, are the best option when there is no room
on the enclosure walls or when the flow rate needed is greater than
what can be provided by the ALFA series of ventilated grilles.
Available air flow rates
There are two different rates: 600 and 1050 m3/h. Radial fans
are used with the motor pin on a bearing. High volumetric efficiency
and quality with an expected life of 50,000 working hours at an
ambient temperature of 25°C.
High protection level
The covering structure’s special labyrinth configuration
and the self-adhesive seal for coupling to the enclosure ensure
the DLK/DLR units an IP44 protection level.
Quick and safe wiring
They are all designed for easy and safe wiring by means of the
terminal block.
Natural ventilating unit
A version is also available without a fan called DLR19XX0A.
This is used when natural ventilation is enough to cool the enclosure
and you want to maintain its high protection level.

Power
supplies available
The DLK ventilation towers are available for single-phase ac
power at 230V and 115V.
On request and for substantial quantities they can also be available
with other voltage not given in the catalogue.
Low noise
A low noise level is one very important factor taken into account
when designing the DLK units. They are in fact designed to minimise
noise disturbance to provide quiet working environments.
Filtering unit
The DLK ventilation towers are used together with the FIL35XN0A
filtering grille for the suction of panel air.
