Important notice: Air compressor is not included. Key benefits and why you need this product: - Provides precise air driven control for handpieces, allowing reliable speed and water regulation for routine instrument use. - Compact control interface with panel and foot pedal options for flexible operation and improved workflow. - Built from stainless steel and durable plastic to withstand regular use and simplify cleaning. What makes this product stand out: - Air control system designed specifically to work with an external air compressor, delivering stable pressure for consistent handpiece performance. - Separate water and air regulation for accurate cooling and spray control during procedures. - Simple connections via quick coupling for the gas supply and a filter inlet for the water supply for straightforward installation. Key specifications: - Control system: air control, requires connection to an external air compressor. - Air pressure for handpiece: 0.01 MPa to 0.4 MPa. - Air pressure input: 4 to 8 kg. - Air pressure output range: 0 to 4 kg. - Water pressure: 0.1 MPa to 0.25 MPa. - Water pressure input: 2 kg. - Water pressure output range: 0 to 2 kg. - Materials: stainless steel and plastic. How to use (concise steps): - Connect the gas source to the quick coupling and connect the water source to the filter inlet. - Attach the appropriate external accessory for the required application. - Turn on the water flow switch to enable water spray. - Use the foot pedal or the panel water supply and the air adjustment knob to set water and air delivery to the required levels. - After use, turn off both the water and air supplies to avoid excessive pressure in the water line. - If the control valve is set to the 4 kg system, no further valve adjustment is required for most instruments under 3 kg; adjust as needed when using heavier instruments. Important handling and maintenance notes: - Do not allow the turbine unit hose to fall onto the floor, because this may prevent proper connection to the handpiece. - To avoid speed overload and to extend service life, set the speed regulator to the minus position before switching power on or off, changing drill rotation direction, or switching between manual and foot pedal control. - Ensure compatible compressor pressure and water supply are used to prevent damage or malfunction. Compatibility and performance: - Designed for use with air driven handpieces and turbines that operate within the stated pressure ranges. - Works with external air compressors that can supply an input pressure between 4 and 8 kg and a water supply capable of the specified input pressure. Practical use scenarios: - General instrument control for a dental operatory that requires precise air and water regulation for air driven handpieces. - Laboratory or workshop bench where controlled air driven rotation and water spray are needed for instrument testing or maintenance. - Educational training environments where students practice with air driven tools under supervised and adjustable conditions.
