Insulation Drying

DÖLCO MF-150 Microfilter

Universal microfilter with HEPA H13 and high-performance activated carbon — fits small and large systems

The MF-150 is the most versatile microfilter in the DÖLCO range — it covers small residential drying as well as demanding large-area drying with a single unit. This is made possible by the combined connection variety of 38 mm and 63 mm ports: you can connect smaller M-compressors (RT-M, SKV 230-VM) as well as powerful VL/VXL units or the SKV 400 with its 63 mm hose sizes. The filter core consists of two stages: the HEPA H13 particulate filter with 99.95% separation efficiency and a **very powerful activated carbon filter**. Activated carbon binds odors very effectively — important after prolonged water damage, where musty, moldy, or chemical odors escape from the insulation layer alongside dust. The MF-150 turns the extracted drying air into hygienically safe and odor-neutral room air. On the top side, 9 × 38 mm connections are available; on the suction side, there is an additional 1 × 38 mm + 1 × 63 mm connection — flexible for any hose configuration. In large-scale system setups, it is typically used with the WVA-7000 and SKV 400 or RT-180 DUO; in residential setups, it is used directly on the RT-M or SKV 230-VM.
