Piston compressor AIRSTAR 903/10 Silent

• Maintenance-free direct drive
• Low space requirements and energy costs
• Low noise level
• Generously dimensioned cooler
• Easy installation and accessibility of all maintenance positions

Coaxial screw-type compressor with maintenance-free drive and maximum energy efficiency in all pressure ranges. Low compressor speeds and low load on the bearings of the patented direct drive ensure a very long service life.

• Prevents motor overload, reduces wear and makes for a longer service life
• Monitoring of operating hours, temperature and motor overload
• Phase sequence relays control the direction of rotation of the motor, thereby avoiding possible damage during commissioning or after relocation

• Low-noise centrifugal fan guarantees optimal operating temperatures even under unfavourable conditions
• Thermostatically and electronically controlled fan and generously sized heat exchanger result in a longer service life and less fluctuation in oil temperature

• Low noise, suitable for deployment in any work environment
• Small footprint facilitates transport and deployment
• Service-friendly thanks to optimum accessibility and easy removal and installation of all components that require maintenance
• All air and oil lines are made of heat-resistant rubber
• Equipped with a star delta circuitry as factory standard
• Ready to connect with all fittings and safety equipment

• More reliable compressed air system without costly downtimes and production delays while simultaneously ensuring product quality
• Fully integrated into the housing
• Ready for use without installation overhead
• Equipped with control panel and time-controlled condensate drain

Special

• Drying by partial vapor pressure compensation of water vapor by diffusion in combination with a highly selective membrane
• No change in the compressed air composition - can be used for breathing air treatment

Efficient

• Reaches the required pressure dew point with low energy consumption
• Very fast availability of dried compressed air
• Filtration and drying compact in one device

Robust

• Housing made of seawater-resistant aluminum
• Low-maintenance, currentless technology

System-compatible

• Modularly combinable with CLEARPOINT Filter program
• Can be used anywhere along the compressed air treatment chain - can also be integrated into system technology

• The ultimate membrane dryer technology with integrated nanofilter
• Filtration and drying in one housing (simple filter element change)
• Low purge air requirement (Twist 60 technology)
• Availability of dried compressed air immediately without running-in phase
• Safe drying due to the high partial vapor pressure gradient
• No change in the compressed air temperature and composition
• Proven 100,000 times
• Maintenance-free (except filter element change)
• For diverse applications, including for breathing air treatment
• Also ideal for use directly behind the compressor / aftercooler
• Optionally also for higher loads (assembly potting, 16 bar, 70°C)
• For a reliable function of the DRYPOINT M membrane dryer must meet the following requirements:
1. The incoming compressed air must not contain any liquid condensate
2. Particles larger than 1 μm must be separated before the membrane dryer
3. The oil content of the compressed air must not exceed 0.01 mg/m³.

• DRYPOINT M membrane dryers have been an alternative to existing ones for years Compressed air drying process proven.

Advantages DRYPOINT M PLUS

• Proven process of highest reliability and functional safety
• Immediate availability of dry compressed air, even when working discontinuously
• Low purge air requirement, compressed air drying can be adjusted to the application
• Compact and robust, small space requirement due to low overall height
• Compressed air inlet and outlet on one level (filter version), easy to combine with CLEARPOINT filters
• Maintenance and wear-free as there are no moving parts
• No reduction in the oxygen content, therefore also suitable for breathing air treatment
• No electrical connection, also suitable for Ex areas
• Long service life in case of use of CLEARPOINT filters
• Environmentally friendly, does not require CFCs / CFC-containing refrigerants or adsorbents
• Complete solution: filtration and dryer in a compact form, integration of drain pipe
• Filtration at the point in the treatment chain where the highest efficiency is achieved
• Easy maintenance / replacement of filter element as with a regular filter

Filter element: N (nanofilter)

• The CLEARPOINT filter element type N is used to separate solid particles down to 0.01 micron, water and oil aerosols . The element has a multi-stage structure for efficient and long-lasting filtering. In the first stage, coarse particles are retained by a pre-filter layer. In the second stage, finer particles are absorbed by a depth filter bed made of high-performance borosilicate fiber fabric. Due to the very large cavity volume of the filter medium (96%), a very high dirt holding capacity is achieved. The filter medium is specially impregnated in order to avoid cross-sectional swelling of the individual fibers.

Trap: Float trap

• The basic version includes a float drain.

Size 10 - 40

• This size is for the demand-oriented compressed air drying of medium volume flows configured. Different levels of drying of the compressed air are achieved through different purge air settings.
