The CompAir L23–L29 RS (22–30 kW) belongs to the lubricated rotary screw air compressor segment—typically used in continuous-duty industrial environments like manufacturing, automotive, packaging, and heavy pneumatic tool operations.
Key Specifications
Power range: 22–30 kW (≈30–40 HP)
Type: Oil-lubricated rotary screw compressor
Models: Fixed speed + RS (regulated/variable speed) versions
Airflow: Up to ~5.4 m³/min depending on model
ضغط (pressure): Typically 5–13 bar
⚙️ What makes the L-Series stand out?
1. Energy efficiency focus
Uses a high-efficiency airend with slow rotational speed to reduce energy consumption
RS (variable speed) models adjust output to demand → major power savings in variable-load operations
2. Reliable industrial design
Integrated oil filter & regulation system reduces external piping → fewer leak points
High-quality components + IE3 efficiency motor ensure long service life
3. Compact & low maintenance
Small footprint for factory floors
Easy access to service parts like filters and separators
Lower lifecycle cost due to optimized maintenance design
4. Smart control system
Delcos Pro / Pro SE controller:
Real-time monitoring (pressure, temperature, run hours)
Service alerts & fault logs
Remote control & automation capability
🏭 Typical Applications
CNC machines & manufacturing lines
Automotive workshops
Packaging & bottling plants
Textile & plastic industries
Continuous air-demand systems
Rotary screw compressors like this are preferred because they provide continuous, stable airflow with less vibration and downtime compared to piston compressors.
💰 Price Range in India (indicative)
Entry listings: ~₹2–5 lakh (basic or used units)
Industrial configured systems: ₹7–20+ lakh depending on:
RS (VFD) vs fixed speed
Integrated dryer / accessories
Brand-new vs refurbished
🧠 Should you choose L23–L29 RS?
Good choice if:
You run operations 8–24 hours/day
Air demand fluctuates (→ RS saves electricity)
You want reliable, low-maintenance industrial air supply
