Pfannenberg PF 32000 230V IP54 Filterfan, 98-108 m3/h

PF 32000 230V IP54 filterfan: decoded article 11632101055

The PF 32000 230V IP54 is a installation size 3 filterfan with 230 V AC supply from Pfannenberg, intended to move cabinet-external air through a filter mat and into an electrical enclosure. It is built into a door or side panel cut-out and removes heat by exchanging the warm enclosure air for cooler ambient air, so it only works when the surrounding air is cooler than the maximum acceptable temperature inside the cabinet.

The model name decodes as follows: PF is the filterfan family, 32000 identifies installation size 3 (the cut-out and airflow class), 230 V AC is the supply voltage and IP54 is the protection class of the filterfan face. The full order number for this exact variant is 11632101055. This size-3 unit is the mid-small workhorse of the family, with 98 to 108 m³/h of free airflow and only 19 W of electrical draw.

Technical specifications of the PF 32000 230V IP54

Data are from the product page for article 11632101055. The page lists approvals cURus, EAC and CAS for the filterfan series.

How the PF 32000 230V filterfan works

It sits between the PF 22000 and the PF 42500 in the series. At 202 mm square on the face it fits typical control cabinets and motor starter panels, and with a standard filter mat it is the economical IP54 option when the site air is moderately clean.

In the PF 32000 230V IP54, air enters through the louvred front cover, passes through the filter mat and is pushed into the enclosure by a single axial fan. Warm air leaves the cabinet through a second opening, usually fitted with a matching exhaust filter, so that dust cannot enter through the outlet either. The louvres are shaped to give a high airflow for the size of the housing and to keep splash water and falling debris away from the filter mat.

Because the PF 32000 230V IP54 only moves air, the achievable cooling depends on the temperature difference between the inside and the outside of the enclosure and on the pressure drop of the filters and any rainhood. A thermostat is normally used to switch the fan on at a set cabinet temperature, which saves power and extends filter life.

Fit in the system and related Pfannenberg parts

Wiring is via a terminal strip, not the flying lead found on the size-1 unit, which makes field connection easier on thick cabinet doors or when the fan is replaced.

The same family covers installation sizes 1 to 6, with sibling models such as PF 11000, PF 22000, PF 32000, PF 42500, PF 43000, PF 65000 and the slim PF 67000 SL. The exhaust counterpart carries the PFA prefix and shares the cut-out, so a filterfan and an exhaust filter of the same size can be combined for forced circulation.

Selection and ordering checklist for the PF 32000 230V IP54

Before ordering the PF 32000 230V IP54, confirm that the following points are settled so the correct variant is quoted:

• Cabinet heat load in watts and the permitted internal temperature
• Highest outdoor or room air temperature; a filterfan only cools when ambient is below the enclosure limit
• Supply: 230 V AC; other voltages carry other article numbers
• Cut-out of 177 mm x 177 mm and the installation depth behind the panel
• Choice between IP54 (standard filter) and IP55 (fluted filter, UV-resistant) for the same size

If the heat load in the panel is above roughly 100 W and the cabinet stays within a few degrees of ambient, a size-3 unit with an exhaust filter is a typical starting point; larger loads may justify size 4 or a cooling unit.

Installation, commissioning and maintenance of the PF 32000 230V IP54

Installing the PF 32000 230V IP54 uses a cut-out in the cabinet wall and the tool-free four-corner fastening of the Pfannenberg filterfan. A poured foam seal on the frame is pressed against the panel, which keeps the stated protection class intact without a separate gasket. Mount the fan so that the airflow is from outside to inside and place the exhaust outlet as far from the inlet as practical, ideally at the opposite side and higher up, so warm air rises out of the enclosure.

Connect the PF 32000 230V IP54 supply with the fuse stated in the data table and protect the circuit as described in the manual. For commissioning, run the fan for several minutes and confirm direction of air movement at the louvres, then check the enclosure temperature under real load.

• Inspect the filter mat at each service visit and replace it when visibly loaded; spare mats come in packs of five
• Verify that the exhaust opening is clear and that cables do not obstruct the louvres
• Terminal strip wiring should be re-checked for tightness after the first thermal cycles on site

This 230 V AC variant suits panels where a mains supply is already present for lighting or sockets. For 24 V DC control cabinets without mains, request the DC article 11632801055 instead, so that the fan is not powered from an additional transformer.

Typical applications in Oman and the GCC

Standard applications include motor control centres, PLC panels, drive cabinets and package-unit control boxes where the ambient air is clean and cooler than the enclosure limit.

Across the region, filterfans are used on control panels in oil and gas facilities, power stations and substations, desalination plants and petrochemical sites, where cabinets sit in electrical rooms or outdoor kiosks. Ambient temperatures above +40 °C for much of the year, fine sand and high humidity near the coast mean that the filter mat class, the protection class and the thermal margin should be checked rather than assumed. Where outdoor ambient air can approach the allowed enclosure temperature, a cooling unit or heat exchanger is the better choice than a filterfan.
