DELAIR Product Lines We Repair
Our engineers are trained on the full DELAIR product range. Below are the major product families we service.
Delair DAC Oil-Free Rotary Screw Compressors
Delair DAC series delivers oil-free compressed air for critical applications in pharma, food, and electronics. Common repair issues include motor bearing wear, valve plate degradation, capacity control valve failure, and thermal valve malfunction leading to pressure loss.
Delair Dry Screw Vacuum Pumps
Delair DVSK and DVS vacuum pump lines are used in packaging, medical device manufacturing, and industrial automation. Typical faults include rotor wear, seal leakage, back-pressure relief valve sticking, and motor overload trips during high-vacuum operation.
Delair Air Treatment and Drying Systems
Refrigerated dryers, adsorption dryers, and filtration modules. Repair scope includes compressor motor faults, electronic control board failures, solenoid valve malfunction, and sensor errors affecting dew point regulation.
Delair Intelligent Control and Monitoring Systems
Delair integrated controllers and IoT-ready monitoring units for network compressor management. Common failures: PLC firmware corruption, Ethernet interface breakdown, pressure transducer drift, and temperature sensor malfunction.
Delair Variable Speed Drive (VSD) Compressors
Delair DAS VSD range optimises energy consumption for fluctuating demand in textile mills, automotive plants, and food processing. Repairs include VFD fault diagnostics, soft-start contactor failure, pressure regulator calibration, and motor winding insulation breakdown.
Delair Portable and Mini Compressor Range
Delair portable oil-free compressors for field service, construction, and mobile industrial applications. Common issues: motor thermal overload, unloader valve stuck, intake filter blockage, and check valve failure causing pressure drop.

Common DELAIR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DELAIR equipment arriving at our workshop.
- ✓Delair compressor motor thermal overload and shutdown — High ambient temperature, inadequate cooling airflow, or motor bearing friction from oil ingestion or wear. Delair oil-free units are sensitive to inlet air filter blockage causing excessive motor load.
- ✓Delair pressure regulation and unloader valve failure — Sticky pilot-operated unloader valve due to compressor oil carryover or contaminant buildup. Delair's capacity control valve requires precise pilot pressure, and seal wear reduces responsiveness.
- ✓Delair refrigerated dryer compressor failure and no dehumidification — Refrigerant leak from corroded heat exchanger tubing, faulty expansion valve, or compressor motor winding burnout from liquid slugging. Delair DDHC dryers rely on precise refrigeration cycle balance.
- ✓Delair PLC and control module fault codes and no response — Firmware corruption from power surge or incomplete software update in Delair DCP control modules. Memory retention battery depletion, I/O connector oxidation, and sensor input signal loss also trigger lockout.
- ✓Delair VSD drive fault with motor speed not matching demand — VFD capacitor ageing and burst in Delair DAS VSD units, pressure transducer calibration drift sending incorrect feedback, or soft-start thyristor failure preventing smooth ramp-up.
- ✓Delair vacuum pump rotor damage and oil contamination in pump outlet — Foreign particle ingestion from intake filter bypass, rotor bearing wear allowing metal debris generation, or dry-running due to inlet valve failure. Delair DVSK vacuum units are prone to carryover if rotor clearance exceeds spec.

Frequently Asked Questions — DELAIR Repairs
Do you repair Delair compressors and dryers across all of India?+
Yes, absolutely. Synchronics maintains a PAN India repair network for all Delair product lines—oil-free rotary screw compressors, vacuum pumps, refrigerated dryers, and intelligent control modules. We offer same-day pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and 50+ Indian cities. All repairs are handled at our Vadodara, Gujarat facility with 180+ engineers.
What is your typical repair turnaround time for a Delair compressor motor or VSD fault?+
Standard Delair compressor motor and VSD drive repairs take 7-10 working days including component sourcing, bench testing, and full performance validation. Critical breakdowns in automotive or pharma plants qualify for 48-hour emergency turnaround at expedited rates. We provide on-call technical support during repairs.
Can Synchronics repair Delair DCP PLC and smart control modules with firmware updates?+
Yes. Synchronics is authorised to reprogram Delair DCP control modules and smart gateways using latest OEM firmware. We backup your existing configuration, perform full diagnostics, reflash memory if corrupted, and validate all I/O functions including pressure transducers, solenoid valves, and motor starters before handover.
What warranty do you offer on Delair compressor and vacuum pump repairs?+
Synchronics provides 12-month comprehensive warranty on all Delair repair jobs, covering labour and replaced components. Warranty includes on-site diagnosis of repeat faults within 48 hours. For critical production equipment, we offer optional 24-month extended warranty and preventive maintenance contracts.
How do you handle Delair oil-free compressor contamination and seal replacement?+
Oil-free Delair compressors like DAC series require precision seal and rotor clearance management. Synchronics disassembles the compressor, ultrasonically cleans all cavities, replaces all elastomer seals and thrust bearings, measures rotor backlash with dial indicators, and reassembles in a controlled environment. We validate oil-free output with particle count testing.
How do I send my DELAIR unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DELAIR drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DELAIR repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DELAIR unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
