Overview
The Coltri ICON LSE Portable Breathing Air Compressor is a compact high-pressure compressor designed for applications requiring breathable air, including scuba diving, recreational use, firefighting services, and paintball facilities. Its relatively small size and portable design make it suitable for users who need high-pressure breathing-air capability without a large stationary compressor installation.
The ICON LSE is available in multiple electric configurations, including single-phase and three-phase models with charging rates up to 100 l/min. Depending on the selected setup, the compressor can be configured for 230 bar or 330 bar working pressure and supports breathing air to EN 12021 as well as Nitrox up to 40% O2, helium, and nitrogen.

Charging Rate Measurement: Charging rates are measured while filling a 10-liter cylinder from 0 to 200 bar at an ambient temperature of +20°C, with a tolerance of ±5%.
Weight & Dimensions: Listed values apply to the standard configuration. Weight and dimensions may vary depending on selected accessories and equipment.
Electrical Configurations
The listed model configurations use 230 V / 50 Hz single-phase power for the 50 EM and 100 EM, while the 100 ET uses 400 V / 50 Hz three-phase power. Other operating voltages listed by Coltri include 230 V / 50 Hz, 440 V / 60 Hz, and 230 V / 60 Hz configurations.
On three-phase electric motors operating at 60 Hz, Coltri states that motor power in kW / HP increases by approximately 20%.

What pressure can the ICON LSE fill to?
The compressor can be configured for 230 bar or 330 bar operation, with a maximum working pressure of 330 bar.
Can the ICON LSE be used with Nitrox?
Coltri lists the compressor for Nitrox applications up to a maximum of 40% oxygen.
What cylinder connection is included?
One connection is supplied and selected from DIN 232, DIN 300, or INT / YOKE 232 bar.
Is the filling hose included?
Yes. One 1.2-meter filling hose is included as standard equipment.
Do all models include an hour counter?
No. The supplied information specifies the hour counter for single-phase electric motor models only.
What oil does the compressor use?
Coltri specifies Synthetic Coltri Oil ST 755 with a stated oil change interval of one year or 50 operating hours.
Expert Insight
The ICON LSE is best selected by matching the charging rate, electrical supply, working pressure, and cylinder connection to the intended installation. The 50 EM offers the lower charging rate in a single-phase configuration, while the 100 EM doubles the charging rate while remaining single-phase. The 100 ET provides the same 100 l/min charging rate using a three-phase motor.
