Piston compressor AIRBOY SILENCE 221 OF E

• With potential-free alarm contact

• Indication of whether the filter element is still functional or needs to be replaced - recommended replacement of the filter element from a pressure drop of 0.6 bar (beginning of the red area on the display)
• For mounting on the upper filter cover

• Innovative LOGIN control with 4.3" touch screen for easy operation and complete control over all functions
• Connection of up to eight compressors possible, no matter if with constant or variable speed
• All information on current operating status at a glance
• Rotation direction control for the motor, prevents damage during start-up or after a change of location
• Low noise emission (only max. 67 dB) during operation, due to extremely low speed of the screw compressor and use of a low-noise radial fan
• Optimum operating temperature and low fluctuation of oil temperature due to thermostatically controlled centrifugal fan, optimum cooling air flow and generously dimensioned heat exchangers
• Aftercooler reduces the effort for drying and filtration of the generated compressed air
• Star-delta switching as standard
• Easy to service: simple removal and installation of all components requiring maintenance

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.
