LK3321 fan and filter
Cabinet Ventilation, LK series UL94V-0 plastic Filter Fan for panel
Linkwell LK33 series fan and filter are designed for the cooling and ventilation of cabinet enclosures. The filter fans are quick and easy to fix (Either click fixing or screw mounting), to form a seal upto IP54 filter fan. The long life expectancy , quiet operation,ultra-thin louvre filter and low maintenance design makes them almost “fit and forget”. For more harsh condition replacement filter mats are available. With multiple voltages for ac dc axial fans, different air flow volume and dimensions, economic types, Linkwell Electric are China leading manufacturer and exporter of filter fans.

Cabinet Top mounting Ventilator
Technical Explanation
The premise of using top-mounted fan:
Ambient temperature should be lower than
the temperature that is required to be in the switchboard.
Take top-mounted fan into account, when
there isn’t enough space for a side-mounted filter fan in the cabinet.
Top-mounted fan of the cabinet will bleed
the air from the top of the cabinet and drive the heat out so as to protect the
electric apparatus and keep them running at the temperature within controllable
ranged. And the structure is more proper because it won’t take up space in the
cabinet.
EN 60 529/10.91 reaches IP54. The retractable
high-power centrifugal fan is able to prevent moisture as well as mechanical
damage, with its labyrinthine rain-proof structure, which with the help of the
sealing frame, can reach an IP code up to IP54 as per EN60529/10.91. The centrifugal
fan is mainly useful for discharge of high-heat load at peak efficiency.
Adoption of the centrifugal fan will be
able to reduce the noise resulting from air friction as well as avoiding the
vortex discharged by normal shaded pole fan.
The quantity and dimensions of inlet
filters could be determined according to the actual situation. Please mark B
behind corresponding model if a stainless shell required.
We can provide products with different
voltage as required by clients.
Using Lk33 or EF Series Exit Filters at the
side of the cabinet can prevent water and dust entering the cabinet, also make
the air through the whole cabinet for cooling.
