A TOP-AIR air filter pre-cleaner prevents dirt particles from reaching the air filter and engine via the air intake, permitting the engine to `breathe freely` for extended periods. The TOP-AIR air filter pre-cleaner is wear-free, thanks to its ball-bearing, high-grade steel tube and polished aluminium hood. The product comes with a guarantee period of up to 6 years.

Oil contamination from metal abrasion, dust, sand, etc. damage the entire system. Metal abrasion causes oxidation processes in the oil. The oil-insoluble particles lead to material abrasion on valve seats and bearing shells. To remove the particles, the TOP OEL® fine engine oil filter is used as a depth filter with a filter fineness of 1 micron.

With the help of fine filtration, particles smaller than 5 μm (5/1000 mm) are removed from the hydraulic oil.

TOP-DRYTM products are manufactured under ISO-9001 certified quality system. They are available around the world through a service-intensive distributor network committed to technical-support and total customer satisfaction. TOP-DRYTM - breathers can be filled with a hygroscopic agent, active coal or a mix of hygroscopic agent an active coal. Unique is the possibility of a costume made filling of the breathers. TOP-DRYTM - filter moisture and particle accumulation are major factors of oil contamination in industry equipment. Neglected, these detriments restrict equipment efficiency, causing machine downtime and significant expense in replacement oil, parts and repair labour. The TOP-DRYTM – breathers remove water vapour and contamination up to 2 micron.

TOP-LUFT® air filter pre-separator can extend the service life of the air filter cartridge by up to ten times by filtering out the impurities in the air before they reach the engine filter.

Oil bath air filter combined with TOP-LUFT® air filter pre-separator. Downstream of the TOP LUFT, the oil bath air filter filters dusts below 5μm from the air and thus guarantees an air purity of 1-5μm. Now available up to 52 m³ / min.

The desire to improve the breathing air in the cabin not only follows the requirements of occupational health and safety, but also the fundamental concern about the well-being of the operating personnel. The ventilation used here, under the name CAB-AIR, works almost silently, so it does not have a disruptive effect on the operator.

Suitable for removing water and suspended matter from fuels and hydraulic fluids. Top clean diesel and fuel filterfilter pre-separator. As engine technology improved, the need for pollution-free fuel increased. This situation required the development of special filters not only for engines but also for fuel dispensers. The TOP CLEAN fuel filter is such a filter for fuel dispensing devices.

The QTM-701 is an electronic measuring instrument for checking physical and electronic changes in liquid lubricants (unalloyed and high-pressure oils) for internal combustion engines as well as gear and hydraulic oils.
