- Confirm ventilation clearances and service space on all sides.
3. Utilities and infrastructure
- Verify voltage, phase, and available amperage.
- Confirm breaker size, wire size, and grounding point.
- Review condensate routing and oil water separation method.
4. Risk and safety
- Confirm lockout points and site safety requirements.
- Review hot work or confined space rules where applicable.
Deliverables before day one

Room Layout and Environmental Requirements
| Element | Requirement | Why It Matters |
|---|---|---|
| Ventilation | Intake air within 10 degrees of ambient outdoors. Exhaust air routed out of room. | Cooler operation increases efficiency and prevents nuisance trips. |
| Clearance | 3 feet on service sides. 6 feet at panels. | Safe access for filters, belts, and coolers. |
| Floor | Level, smooth, and oil resistant. Anchors where specified. | Stable mounting limits vibration and movement. |
| Noise | Isolation pads or mounts when close to people. | Reduces transmitted vibration and improves comfort. |
| Contaminants | Keep away from paint fumes, solvents, and dust. | Protects intake filters and prevents oil degradation. |
| Condensate | Drain lines pitched to collection point with traps. | Environmental compliance and dry floors. |
⸻
Electrical and Controls Integration
- Provide a dedicated circuit sized to nameplate current and NEC guidance.
- Install a lockable disconnect within sight of the unit.
- Verify rotation on first start with a bump test.
- For VFD units, confirm line reactors or filters as recommended by the manufacturer.
- Land control wiring for remote start and stop, lead and lag sequencing, and alarms.
- Label control conductors and document terminal numbers in the startup report.
Power quality checks
- Measure voltage, phase balance, and available fault current.
- Record inrush and running amps at full load during commissioning.
⸻
Piping, Filtration, and Storage
- Use aluminum or black iron pipe sized for flow with velocity targets under 20 feet per second on mains.
- Create a looped header where possible for balanced pressure at drops.
- Provide flex connectors at the compressor and the dryer to protect equipment from strain.
- Install a minimum of 25 feet of cooling run or an aftercooler before primary filtration on piston units.
- Place prefilters, coalescing filters, and particulate filters in sequence with gauges to track differential pressure.
- Size the receiver at 4 to 5 gallons per cfm for piston duty and 2 to 3 gallons per cfm for rotary screw where cycling control is used.
- Install automatic drains at low points and at the receiver.
⸻
Dryer and Air Quality Selection
| Goal | Typical Solution | Notes |
|---|---|---|
| General shop air | Refrigerated dryer with 38 degree dew point | Protects tools and finishes in most environments. |
| Instrument or paint lines | Coalescing prefilter and point of use filter | Keeps oil and particulates out of sensitive devices. |
| Low dew point requirements | Heatless or heated desiccant dryer | Select purge saver controls to reduce energy cost. |
| Oil sensitive processes | Oil vapor filter and suitable lubricant selection | Verify compatibility with downstream products. |

Commissioning and Startup Procedure
1. Pre start inspection
- Verify model and serial numbers against submittals.
- Confirm oil type and level.
- Inspect belts, guards, fasteners, and wiring terminations.
- Check rotation direction and ventilation path.
2. Controlled startup
- Energize control power and check the HMI for faults.
- Bump test for rotation.
- Start the unit under no load and listen for abnormal noise.
- Load the unit gradually while monitoring pressure, temperature, and amps.
3. System validation
- Verify pressure at the header and at the farthest drop.
- Record discharge temperature and dew point after stabilization.
- Check filter differential pressure and drain function.
- Confirm safety shutdowns and alarms.
4. Documentation and training
- Deliver a startup report with readings, torque values, and settings.
- Review maintenance intervals and daily checks with operators.
- Provide a spare parts list and recommended onsite inventory.

Sample Startup Readings Captured
| Reading | Value Target | Notes |
|---|---|---|
| Discharge pressure | Within set band for application | Verify setpoints match process needs. |
| Discharge temperature | Within manufacturer spec | High values indicate airflow or cooler issues. |
| Dew point | At or below specification | Confirms dryer performance. |
| Filter differential | Under changeout threshold | High values reduce pressure at tools. |
| Amps per phase | Balanced and under nameplate | Imbalance can signal wiring or motor issues. |

Warranty Protection and OEM Practices
- Follow torque values, belt tension, and fluid specifications from the manufacturer.
- Use OEM grade filters and lubricants unless you direct a vetted equivalent.
- Record hours and initial operating conditions to support warranty claims.
- Keep a copy of the startup checklist with photos of serial tags.
⸻
Safety and Compliance
- Lockout tagout for electrical and mechanical isolation.
- Arc rated PPE for work inside energized enclosures when permitted.
- Spill control kits for oils and condensate.
- Proper storage and labeling for removed parts and used filters.
- Housekeeping after work so the room is clean and safe.
⸻
Owner Training and Handover
- Daily checks for oil level, temperature, and abnormal noise.
- How to read the controller for alarms and maintenance intervals.
- Filter change triggers based on differential pressure.
- Drain inspection and how to test cycle function.
- Basic leak detection and reporting.
⸻
Energy and Reliability Improvements During Installation
- Right size the header and drops to limit pressure loss.
- Lower pressure setpoints where the process allows.
- Add storage capacity to reduce short cycling on fixed speed units.
- Use zero loss drains where fit for purpose.
- Sequence multiple compressors for balanced runtime.
- Plan for future growth with space and electrical capacity.

Frequently Asked Questions
How long does a typical installation take
Most single units with dryer and receiver are completed within one to three days once the pad, power, and penetrations are ready. Multi unit projects and long piping runs take longer. A clear schedule is provided before work begins.
Do you coordinate rigging and disposal
Yes. We can schedule rigging, removal of old equipment, and delivery of the new package. Disposal is handled in line with your site policies.
Can you work after hours
Yes. We offer overnight or weekend work when production cannot stop during the day.
What information do you need up front
Process requirements, voltage and service capacity, desired air quality and dew point, site rules, and target dates. Photos of the room help with planning.
Do you install piping to the farthest drop
Yes. We can install full header loops, drops, regulators, and quick connects, or we can terminate at a specified flange for your maintenance team.
