Rittal 3239110 – Frequently Asked Questions

1) Which Rittal 32391 filter fan should I order for a 24V DC control panel versus a 115V AC panel?
Two supply voltages are built on the Rittal 32391 TopTherm filter fan unit, and you pick by what your panel feeds: part number 3239124 is the 24V DC version, and 3239110 is the 115V AC version (single phase, 50/60 Hz). There is no universal unit, so match the part number to the control voltage already in the cabinet.
2) Is an IP54 filter fan good enough for a washdown or outdoor enclosure?
Not as shipped. The 32391 TopTherm unit comes IP54 to EN 60529 / IEC 60529 with the fleece filter mat, which is dust and splash protection equivalent to NEMA Type 12 for indoor panels. To go further you add accessories: folded filter plus absorber mat raises it to IP55, and a hose-proof hood with fleece or folded filter gets you IP56 and NEMA Type 3, 3R, 4 and 4X. If the location is washed down or exposed, you must order the hood, not just the fan.
3) What ships in the box with the Rittal 32391 filter fan, and what do I have to buy separately?
Each unit ships complete and ready to install with a fleece filter mat, so nothing extra is needed for a standard IP54 indoor install. Buy separately if you need more airflow (the optional folded filter increases air throughput), higher protection (absorber mat for IP55, hose-proof hood for IP56 / NEMA 4X), and the 2A pre-fuse or miniature circuit breaker on the supply circuit.
4) What size circuit protection does a TopTherm filter fan unit need?
Protect the supply with a 2A miniature circuit breaker or fuse ahead of the unit. That pre-fuse rating applies to both the 24V DC and the 115V AC versions, and it is a small enough draw to land on a spare pole in most control panels.
5) Will a filter fan alone cool my enclosure, or do I need an air conditioner?
A filter fan moves ambient air through the cabinet, so it only works when the surrounding air is cooler than the target temperature inside. The TopTherm unit covers 20 to 900 m3/h of throughput with an axial fan and shaded pole motor, which handles typical control panel heat loads in normal plant and indoor conditions. Where ambient air is hot, dirty beyond what a filter mat can handle, or the panel must stay sealed, a closed-loop cooling unit is the right choice instead of a filter fan.
6) What temperature range can a Rittal TopTherm filter fan unit operate in?
Operating range is -15 C to 55 C, with storage from -30 C to 70 C. That covers unheated industrial spaces and protected outdoor cabinets, but note that in freezing conditions the fan is pulling outside air straight into the enclosure, so it is ventilation and not heating.
7) Will the fan housing match my existing gray Rittal enclosures?
The housing is finished RAL 7035, the standard light gray used on most industrial enclosures, so it blends with existing cabinet runs rather than standing out on a visible panel face.
