3. Hydraulic & Pneumatic Dental Chair Repair
Most dental chair movement — reclining, height adjustment, and backrest control — is powered by a hydraulic or pneumatic system. When this fails, the chair becomes completely inoperable. Our engineers are trained to diagnose and repair all hydraulic and pneumatic dental chair systems.
Hydraulic System Repairs
- Hydraulic cylinder replacement — the cylinders that power chair height and recline; we carry compatible cylinders for most brands
- Hydraulic seal replacement — worn seals cause slow oil leaks under the chair base; replaced before they cause pump damage
- Hydraulic pump repair or replacement — failed pump motor leaves the chair frozen in position
- Solenoid valve replacement — valves direct hydraulic fluid to the correct cylinder; failed valves cause partial or complete movement failure
- Hydraulic fluid top-up — low fluid causes slow, jerky, or incomplete chair movement
Pneumatic System Repairs
- Airline leak detection and repair — leaking air lines cause loss of pressure to handpieces and scalers
- Pressure regulator replacement — maintains correct working pressure for all pneumatic components
- Air filter and moisture separator service — dirty or saturated filters reduce performance and damage handpieces
- Pneumatic valve replacement — directional control valves for air-driven chair positions
4. Electrical & Control System Repair
Modern dental chairs are controlled by sophisticated electronic control boards that manage all chair functions — positions, water, air, lighting, and handpiece control. Electrical faults can disable individual functions or shut the entire chair down.
- Control board diagnosis and replacement — the central PCB that controls all chair functions; we diagnose board-level faults and replace where necessary
- Foot pedal controller repair — the foot control sends position and function commands; worn contacts, broken cables, or failed switches are all repairable
- Hand controller (touchpad) repair — digital membrane controllers and button panels for chair function selection
- Wiring harness inspection and repair — cracked insulation, corroded connectors, and broken wire runs are found and repaired
- Transformer and power supply repair — the internal transformer steps down mains voltage for the chair electronics; a failed transformer disables all electrical functions
- Fuse inspection and replacement — blown fuses protect circuits; we identify the underlying fault before replacing
5. Dental Compressor & Suction Unit Repair
The dental compressor and suction unit are the two most critical ancillary pieces of equipment in any dental clinic. Without clean, dry compressed air and effective suction, the dental chair cannot function.
Dental Compressor Repair & Servicing
- Compressor motor repair or replacement — motor failure causes complete loss of air supply to all handpieces
- Pressure switch and regulator replacement — ensures correct working pressure is maintained
- Air tank inspection and draining — moisture buildup in the air tank corrodes the tank and contaminates air supply
- Air filter replacement — intake and outlet filters require regular replacement to maintain clean dry air
- Belt and piston service — worn pistons and drive belts reduce compressor output pressure
- Oil-free compressor service — specialized service for oil-free dental compressors used in infection-control environments
Dental Suction Unit Repair & Servicing
- Suction motor replacement — failed motor causes complete loss of saliva ejector and high-volume evacuator function
- Amalgam separator service — mandatory for clinics working with amalgam; separator requires regular emptying and cartridge replacement
- Suction line blockage clearing — debris and biofilm accumulate in suction lines, reducing suction power over time
- Suction valve replacement — worn valves allow backflow of contaminants
6. Dental Chair Upholstery Repair & Replacement
Torn, cracked, or stained upholstery on a dental chair is both a hygiene risk and a negative first impression for patients. We replace and repair all dental chair upholstery using clinical-grade, autoclavable-compatible vinyl materials.
- Seat cushion replacement — full seat pad replacement with high-density foam and clinical vinyl cover
- Backrest upholstery replacement — full back panel reupholstery matched to chair color and specification
- Headrest pad replacement — disposable or permanent headrest pad replacement
- Armrest cover replacement — worn or torn armrest pads replaced with matching clinical vinyl
- Full chair reupholstery — complete chair upholstery replacement where multiple panels have failed

11. What Our Clients Say
Our dental chair completely stopped reclining on a Monday morning with a full patient schedule. Quelle Technologies arrived within 3 hours, diagnosed a hydraulic solenoid valve failure, and had the chair working again before noon. Exceptional service.
We have a maintenance contract with Quelle Technologies for all three dental chairs in our clinic. No surprise breakdowns since signing up. The quarterly visits keep everything in top condition and the service reports are excellent for our ISO documentation.
Very professional team. They installed two new dental chairs for us from scratch — including all plumbing, electrical, and commissioning. Everything was done neatly and the commissioning report was thorough. Highly recommended.
Honest and transparent pricing — I was quoted before any work started and the final bill matched exactly. The technician explained everything clearly and also identified a compressor issue I wasn't even aware of. Very trustworthy.
