Screw compressor A-PLUS 31-08 K

• Screw compressor with ribbed belt drive
• Start-stop operation via pressure switch, thereby saving energy compared to idling control
• Minimal and easy maintenance
• Ready for connection with all fittings
• Fifteen-year rust-through warranty on inside and outside hot-dip galvanized compressed air tank
• Easily transportable and deployable thanks to the safety pallet.
• KK version as standard with automatic steam trap for the reliable and economical discharge of the condensate without unnecessary loss of compressed air
• K and KK version with refrigeration dryer as standard with pressure dew point at 3 °C, ambient temperature 25 °C

• Enabling the second compressed air vessel doubles the pressure vessel volume, thus creating a greater compressed air reserve. Helps to cover short-term peaks in compressed air requirements
• For, e.g., chisel, hammer or sandblasting work, the second vessel can be isolated from the compressed air supply. This halves the vessel volume helping to build up the pressure more quickly.

• For continuous air demand and discontinuation operation
• Electronic control for reliability and efficiency
• Increased flexibility thanks to two compressed air tanks
• High-quality and expandable equipment
• Smooth and quiet

• Just as mobile and compact as piston compressors, but with the great advantage of being able to generate compressed air continuously without any cooling pauses
• Can also be used in intermittent operation due to oil temperature control

Electronic temperature control for optimum oil temperature

• Optimum oil viscosity due to constant temperature, therefore also suitable for intermittent operation with frequent load changes
• Temperature control of the oil prevents condensation and minimizes wear
• Better energy efficiency compared to a piston compressor with the same delivery capacity
• Additional oil heat exchanger for cooling

K-Tronic electronic control system for reliability and efficiency

• Adjustment of the cut-in and cut-out pressure
• Direction of rotation control
• Monitoring and control of the oil temperature
• Maintenance interval display

Optimized oil separation system

• Effective oil pre-separation by gravity, as the oil sump is located at the lowest point
• Oil separator cartridge and oil filter cartridge easily accessible for maintenance

Integrated design of the compressor unit

• Convenience and high operational reliability thanks to integration and short connections of all key components on the compressor unit
• Maintenance-free direct drive
• Freewheel valve for load-free operation after reaching the set pressure

Lightweight, compact and quiet

• Can be used in mobile applications or where space is limited
• Highly efficient and low-noise fan
• Smooth-running compressor with low noise level

Increased flexibility thanks to two compressed air tanks

• Two 100 liter compressed air tanks ready mounted on a safety pallet
• Doubling of the air supply by switching on the second compressed air tank - an increased air requirement is covered at short notice
• Halving the tank volume by disconnecting the second compressed air tank - allows pressure to be built up quickly, e.g. for chiseling or sandblasting work

High-quality equipment

• Hot-dip galvanized compressed air tanks inside and out with a 15-year guarantee against rusting through
• Splash water protection in accordance with IP 54
• Flexible armored hose lines with heat protection prevent vibration fractures
• With phase inverter on the plug as standard
• Ready for connection with all fittings
• Additional equipment for compressed air preparation and discharge available

• EasyTRONIC MICRO II electronic control with pressure sensor operation as standard, thus preventing motor overload, reducing wear and extending service life
• With star-delta switch
• High cooling effect and lower noise level due to thermostatically controlled radial fan
• Operating hours counter records load and overrun times, thus ensuring compliance with maintenance intervals - Indication of maintenance requirements via automatic message
• Rotation direction control for the motor avoids possible damage during commissioning or after a change of location
• Screw compressor with wear-resistant Poly V ribbed belt drive and slide clamping system
• Easy maintenance due to easily accessible elements
• Optimum operating temperatures due to thermostatically controlled fan, optimum cooling air flow and generously dimensioned heat exchanger, thus longer service life, lower fluctuations in oil temperature than with thermostat control
• Aftercooler as standard, thus less effort for drying and filtration of the generated compressed air
• Small external dimensions, thus easy transport and installation

• Small external dimensions, thus easy transport and installation

• All main components of the compressor are manufactured by machining using numerically controlled machine tools, including suction regulator, separator block and minimum pressure valve
• The cooling takes place via a temperature-controlled centrifugal fan and an oversized combination cooler. This ensures optimal cooling even under the most extreme conditions.
• Generous access panels allow easy maintenance and immediate control of the internal components, reducing the time required for inspection and maintenance to one medium.
• The main operating parameters are monitored by the electronic microprocessor control NRG: In addition to the various functions, a weekly timer for switching on and off is available to meet the requirements of each customer. In addition, up to 4 machines can be controlled simultaneously according to the master / slave principle.
