01 · CompAir service
Service built around the compressor in front of us
CompAir’s industrial range spans small packaged compressors, large lubricated screws, oil-free process-air systems and towable units. The service approach has to follow the design. A pressure problem on an L-Series machine is not diagnosed the same way as an interstage-temperature alarm on a D-Series compressor or an engine fault on a C-Series portable.
Airtek starts with the equipment identification, operating history and actual fault. We can then check the relevant air, oil, cooling, control and drive systems before recommending a repair.
That matters on older equipment too. CompAir has a long industrial history, including documented CompAir BroomWade and Reavell machines. For legacy units, a clear data plate, controller details and photos help establish the correct service path before parts are ordered.
02 · Equipment families
CompAir equipment we can assess
These families reflect CompAir’s industrial catalogue and documented legacy equipment. Exact repair scope and parts availability depend on model, serial number, age and condition.
L-Series rotary screw compressors
Fixed-speed and regulated-speed packages used for plant air, manufacturing, fabrication and other continuous industrial demand. Service may involve separator systems, oil circuits, coolers, inlet regulation, drives, motors and Delcos controls.
Representative families
L02–L37, L45–L75, L90–L132 and large-frame L160–L290 equipment, including applicable FourCore variants
D-Series & Ultima systems
Oil-free compressors for applications where compressed-air quality is critical. Diagnosis can include stage pressures and temperatures, cooling, condensate management, variable-speed operation, sensors and controller fault history.
Representative families
D15–D37, D37–D75, D90–D160, D200–D355 and Ultima U75–U160
C-Series portable compressors
Towable and mobile compressors used for construction, utility, rental, blasting and pneumatic-tool applications. Service can cover the compressor package, engine interface, regulation, shutdown circuits, cooling and air/oil separation.
Representative families
C20–C30, C35-10–C50 and mid- to large-range C-Series portable equipment
Earlier CompAir equipment
Earlier rotary screw and reciprocating machines may remain viable when the condition, duty and repair economics make sense. Airtek reviews the exact unit rather than assuming current-series parts or procedures apply.
Documented legacy examples
Earlier L-Series packages, CompAir BroomWade machines and CompAir Reavell reciprocating equipment such as the BC6
03 · Faster service intake
Send the right machine details first
CompAir names can repeat across generations and configurations. A complete data plate and fault record help us identify the actual package before discussing parts or repair scope.
04 · Common symptoms
What is the compressor doing?
A symptom narrows the investigation; it does not identify a part by itself. Operating the machine after a high-temperature, low-oil-pressure or abnormal-noise shutdown can increase damage.
Low pressure or low flow
Possible areas include inlet regulation, leaks, pressure controls, drive speed, separator restriction or airend condition.
High discharge temperature
Cooling airflow, cooler fouling, oil level and condition, thermostatic control and ambient conditions all need to be considered.
Oil carryover
Separator condition, scavenging, oil level, operating pressure and return-line function can affect downstream oil.
Will not load or unload
Pressure signals, inlet and blowdown components, solenoids, controller logic and leaks may contribute.
Drive or controller fault
Regulated-speed machines require checks of the supply, drive status, motor, sensors, parameters and machine-side load.
Oil-free stage alarm
Interstage pressure or temperature deviations can involve cooling, seals, valves, airends, instrumentation or condensate control.
Portable shutdown
Engine protection, aftertreatment, fuel supply, cooling, compressor temperature and shutdown circuits should be read together.
Air or oil leak
Hoses, fittings, cooler joints, shaft seals, minimum-pressure components and separator-vessel connections may require inspection.
Noise or vibration
Stop and assess new mechanical noise. Bearings, couplings, belts, fans, motors and airends can create different vibration signatures.
05 · Repair process
A clear route from fault to repair
The process is scaled to the machine and problem, from a compact packaged screw to an oil-free multi-stage system.
01
Identify
Confirm the model, serial number, controller, configuration, duty and service history.
02
Diagnose
Reproduce or evaluate the fault and test the systems connected to the symptom.
03
Recommend
Explain the findings, repair scope and any constraints created by age, condition or parts availability.
04
Repair & verify
Complete the approved work, run the equipment where practical and confirm the original issue is resolved.
06 · CompAir service FAQ
Before you book
Useful answers for planning an industrial CompAir repair in the Edmonton area.
Which CompAir compressor families does Airtek work on?
Airtek can assess industrial L-Series lubricated screws, D-Series and Ultima oil-free systems, C-Series portable compressors and selected legacy CompAir equipment. Serviceability depends on the exact model, condition, documentation and parts availability.
Can Airtek service an older CompAir model?
Often, yes, but older equipment must be reviewed individually. Send the full data plate, controller or starter photos, the fault description and any available manual or service history. We will confirm the next practical step rather than assume current parts fit a legacy machine.
Do you repair both fixed-speed and variable-speed compressors?
Airtek can troubleshoot both configurations. Variable-speed faults may involve the electrical supply, drive, motor, controls, sensors or a mechanical load on the compressor, so the displayed fault code is only one part of the diagnosis.
Can you diagnose CompAir oil-free compressor alarms?
Airtek can assess oil-free machine faults, including temperature, pressure, cooling, sensor and control issues. Because oil-free systems can be application-critical and model-specific, we first confirm the machine configuration and operating history.
What should I do after a high-temperature shutdown?
Let the unit cool safely and avoid repeatedly resetting it without finding the cause. Check for obvious ventilation blockage or fluid loss only within your site’s safety procedures, then record the alarm and contact a compressor technician.
Can Airtek help with a CompAir portable compressor?
Yes, Airtek can assess industrial C-Series and other CompAir portable units. Include the compressor and engine model information, because engine controls, emissions systems and compressor protection circuits can interact.
What information helps Airtek quote or schedule the work?
Send the model, serial number, run hours, fault message, recent service history, operating symptoms and clear photos. For intermittent problems, note when the fault occurs: startup, loading, full load, unload or shutdown.
