The new "Mobilair 43" portable compressor PE enclosure


Exceptional Efficiency


The "Mobilair 43" is one of the latest models in Kaeser's highly renowned range of portable compressors to now be offered with a double-walled polyethylene sound enclosure. This versatile machine sets the standard for efficiency and performance in the 4m³ portable compressor class.

One of the first things that strikes you when looking at the "Mobilair 43" is its sleek design: Ensuring long-term value retention, the new corrosion- and scratch-resistant polyethylene enclosure, which features integrated wheelhouses, creates the unit’s dynamic look and discretely hides what lies beneath: impressive performance, energy efficiency and user- / environmentally-friendly operation.

Powered by a four cylinder water-cooled Kubota turbo diesel engine, the “Mobilair 43” provides an impressive free air delivery of 4.2m³/min at 7 bar. A 1:1 maintenance-free direct drive coupling links the ultra-quiet engine and large low speed Sigma Profile airend to ensure minimal sound levels of only 69 dB(A) (Surface sound pressure level measured in accordance with ISO 3744), making the “Mobilair 43” one of the quietest portable compressors in its class.

Furthermore, Kaeser's direct drive system eliminates the transmission losses associated with gear driven units, consequently providing more air for less fuel and extending both motor and airend service life. With an operational weight of less than 750Kg, the unit is compact, easily manoeuvred and service friendly. This aspect also has two further advantages for the European market: Firstly, new drivers do not require an additional towing licence to transport the “Mobilair 43” and, secondly, the unit can be towed in the EU without having to be equipped an overrun brake. Fitted as standard and improving reliability still further, Kaeser’s patented "Anti-Frost Control" is particularly useful at times of the year when ambient temperatures are lower, as it protects air tools against freezing, corrosion and potential damage.

All metallic body components are either galvanised or powder coated to ensure long-term protection from the elements. Operation is made simple via a single control switch and user-friendly icons, whilst excellent component access greatly simplifies servicing and maintenance tasks. Last, but not least, a hose reel (see image) with a lightweight 20-metre hose is available as an optional extra. This accessory enables the compressed air line to be neatly stowed away and eliminates the possibility of it becoming a tripping hazard.
