Filter fans avoid unwanted heat pockets and protect the electronics. Filter fans from Lm-therm are a cost-effective and simple solution for cooling control cabinets. Not only the slide-on filter fan cover, which allows tool-free filter mat replacement, speaks for the use of Lm-therm filter fans, but also the simple and quick installation without screws make Lm-therm filter fans the perfect solution.

Lm-therm offers filter fans in a wide range of sizes. The filter fans can also be used outdoors with appropriate protection, e.g. with our jet water hood.

In addition to filter fans and control cabinet heaters, we offer an extensive range of thermostats and hygrostats. They ensure an optimal climate in the control cabinet. Our temperature controllers are available either as normally closed/NC for controlling heaters or for switching alarms when the temperature falls below the permissible value, whereby the contact opens when the temperature rises, or as normally open/NO for controlling filter fans, heat exchangers, Peltier cooling units and for switching alarms when the permissible internal temperature of the control cabinet is exceeded. In parallel, we also offer other products such as Ex-controllers, IP-protected controllers and special Peltier controllers.

Our Lm-therm LED lights have been specially developed for use in control cabinets. Two connections - Wieland plug or Pushfit - allow individual connection of the control cabinet lights. Integrated magnets and enclosed clips allow an easy and quick mounting.

The following LED lights are available:

• with 400 Lm or 700 Lm
• wide voltage range (24 - 265V AC/DC) at 400 Lm
• with motion detector or ON/OFF switch
• up to 16 luminaires with AC and up to 8 luminaires with DC voltage can be interconnected by means of a connecting cable
