Lifa Air Special Cleaner 20 Brushing Machine for HVAC Duct Cleaning

For small ducts measuring 100-400 mm (3.9 - 15.7"); Continuous adjustment, 225 - 580rpm

Have a small duct? The SpecialCleaner 20 is designed to clean tight spaces. Pneumatic operation by foot control mechanism allows direction of rotation to be changed helping you avoid obstacles.

The SpecialCleaner 20 has a 20m (65.6 ft.) cleaning shaft, which enables it to clean up to 35m (115 ft.) of duct when extended in either direction from one hatch. The SpecialCleaner 20 is extremely handy in tight places, giving it the edge over other cleaning machines. As a small machine, it can quickly be set up for use or transportation. It has an extensive reach and a suitably long feed cable.

The reel for the flexible shaft is designed to wind the slack back into itself to prevent the shaft from coming into contact with dirty floor space during cleaning. The machine is also equipped with two power out tapping points for lights and drills. The rotation direction can be changed using the pneumatic foot control. Changing the direction of rotation enables the user to navigate the brush through bends in ducts.

All Lifa Air brushing machines can clean round or rectangular ducts. The correct choice of brush and cleaning technique ensures that rectangular ducts can also be cleaned.

Connecting Lifa Air’s low pressure cleaning machines to an AirClean 3500, HepaClean 4000 or HepaClean 2500 to the duct ensures the complete removal of all dirt brushed loose in the ventilation duct.
