GRAHAM-WHITE Product Lines We Repair
Our engineers are trained on the full GRAHAM-WHITE product range. Below are the major product families we service.
Airline Filters and Moisture Separators
Graham-White modular filter units remove liquid water, oil mist, and particulate contamination from compressed air lines. Common issues include saturated filter elements, internal membrane failures, and condensate accumulation causing pressure drop and equipment malfunction.
Pressure Regulators and Control Valves
Pilot-operated and direct-acting regulators for stable outlet pressure across varying demand. Graham-White regulators experience seal degradation, diaphragm rupture, and drift under pulsating load conditions common in Indian textile and automotive applications.
Pressure Switches and Sensors
Electromechanical and electronic pressure sensing devices for system monitoring and pneumatic automation. Faults include contact oxidation, set-point drift, and electronic module failures due to moisture ingress in humid Indian industrial climates.
Modular Air Treatment Units (FRL)
Combined filter-regulator-lubricator assemblies for machine tool circuits and pneumatic actuator supply. Typical failures include clogged filter bowls, sticky regulator spools, and lubricator oil starvation affecting downstream tool performance.
Dryer and Desiccant Systems
Desiccant and refrigerant dryer units controlling moisture in compressed air networks. Graham-White dryers fail when desiccant cartridges saturate or refrigerant circuits develop leaks, leading to dew-point degradation and downstream corrosion.
Safety and Check Valve Assemblies
Non-return valves, shuttle valves, and safety relief devices protecting pneumatic systems from backflow and overpressure. Common failures include valve seat corrosion, spring fatigue, and seal leakage under cycling stress.

Common GRAHAM-WHITE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRAHAM-WHITE equipment arriving at our workshop.
- ✓Regulator outlet pressure drift and instability — Graham-White regulators experience diaphragm material degradation or worn pilot poppet seats due to particulate ingress and extended service in dusty Indian factory environments. Seal corrosion from moisture-laden compressed air accelerates pressure set-point loss.
- ✓Coalescing filter element saturation and water breakthrough — Graham-White FHS and FP series filters trap liquid water but the sintered glass fibre media becomes saturated in high-humidity regions (coastal India, monsoon seasons). Condensate accumulation in the bowl creates back-pressure and allows liquid carryover to downstream equipment.
- ✓Pressure switch contact sticking and false actuations — Graham-White PS and PSX series switches experience electrical contact arcing and oxidation when switching 24VDC solenoid loads in dusty Indian automotive plants. Moisture ingress into the switch housing from humid climate causes internal corrosion and set-point migration.
- ✓Modular FRL unit sticking regulator spool and sluggish response — Graham-White FRL200/300 regulator spools develop sticky operation when minute water droplets freeze at the spool guide surfaces, or when mineral deposits from old system oil harden. High ambient temperature fluctuations in Indian factories aggravate spool stiction.
- ✓Desiccant cartridge saturation and dew-point rise above specification — Graham-White desiccant dryer cartridges become saturated when system air flow rate exceeds rated capacity or when bypass valve opens due to high pressure drop. In Indian coastal and monsoon climates, outdoor air intake with high ambient moisture accelerates saturation cycles.
- ✓Safety relief valve chattering and erratic pressure spikes — Graham-White pilot-operated relief cartridges chatter when pilot line tubing contains micro-leaks or when pilot poppet seats accumulate debris. Resonance in the main spring stack occurs if downstream volume or line length creates hydraulic oscillation.

Frequently Asked Questions — GRAHAM-WHITE Repairs
Do you repair Graham-White equipment anywhere in India?+
Yes. Synchronics repairs the complete Graham-White product range including regulators, filters, dryers, pressure switches, and modular FRL units. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other major industrial cities. All repairs are completed at our main facility in Vadodara, Gujarat, which houses calibration benches and test rigs specific to pneumatic control systems.
What should I do if my Graham-White regulator is drifting pressure in production?+
Contact Synchronics immediately for emergency pickup. Regulator drift is often caused by diaphragm wear or pilot poppet corrosion — both critical faults that worsen under load. Do not attempt field adjustment as this compounds the underlying seal damage. Synchronics provides 24-hour turnaround on regulator recalibration using precision test benches that simulate your outlet pressure and flow conditions. We replace internal components with genuine Graham-White seals and validate performance before return.
How often should Graham-White filter cartridges be replaced in Indian climate conditions?+
In coastal regions (Mumbai, Chennai, Cochin) and during monsoon season, Graham-White coalescing and desiccant cartridges should be inspected monthly and replaced every 6-8 weeks. Inland dry regions (Delhi, Ahmedabad, Pune) allow 12-16 week intervals. Synchronics recommends installing moisture indicator cartridges and conducting quarterly air dew-point testing. We supply genuine Graham-White replacement cartridges and offer preventive maintenance contracts with door pickup and cartridge delivery to ensure your FRL and dryer units never exceed dew-point specifications.
Can Synchronics recalibrate Graham-White pressure switches to match my equipment specifications?+
Yes. Synchronics has precision calibration benches for Graham-White PS, PSX, and PXL series switches across 0-10 bar, 0-25 bar, and 0-40 bar ranges. We use traceable pressure sources and recalibrate set-point and hysteresis to your exact engineering drawing requirements. Electronic switches are fully tested on 24VDC solenoid simulation loads before return. Calibration certificates are provided for ISO 9001 and pharmaceutical GMP documentation.
What is the typical lead time for Graham-White component repairs in Vadodara?+
Standard turnaround is 5-7 working days from receipt. Emergency repairs of regulators, dryers, and FRL units are completed in 48-72 hours with rush diagnostics fee. If spare parts (seals, diaphragms, cartridges) are required, we source genuine Graham-White components through our supplier network and extend turnaround accordingly. Synchronics provides real-time repair status tracking via email and mobile updates throughout the repair cycle.
How do I send my GRAHAM-WHITE 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 GRAHAM-WHITE 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 GRAHAM-WHITE 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 GRAHAM-WHITE 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.
