Every compressed air system produces condensate: water from the intake air, mixed with oil and dirt. It must be reliably drained from the compressor, dryer, filters and receivers without losing expensive compressed air, and separated from the oil before disposal.

Why condensate management?
If condensate remains in the system, pipes rust, tools fail and it can freeze in winter. Old float or timed drains also blow off compressed air every time they open.
Oily condensate must not go into the sewer. An oil-water separator retains the oil so that only cleaned water is discharged.
Drains
without compressed air loss
For systems
up to 500 m³/min
Pressure
up to 16 bar, HP up to 80 bar
The product lines
CCNL electronic · CMNL magnetic · CTDV/CTDC timed · CSLV air saver · Oil-water separator
CCNL 10 and 100 – electronic, zero air loss
Level-controlled with alarm function

The electronic drain opens only when condensate is present and closes before compressed air escapes. An alarm signals faults.
- CCNL10 for systems up to 10 m³/min
- CCNL100 up to 100 m³/min
- 0 to 16 bar, HP version up to 50 bar
CMNL 10, 100 and 500 – magnetic, no power needed
Level-controlled, zero air loss and no power connection

The CMNL works with magnetic force instead of electricity and still drains without air loss. The CMNL500 handles 4,800 l/h at 16 bar and is suitable for large systems.
- CMNL10 up to 10 m³/min, CMNL100 up to 100 m³/min, CMNL500 up to 500 m³/min
- No power connection required
- 0 to 16 bar
CTDV and CTDC – timed
Solenoid valve with timer

The CTDV opens at adjustable intervals. The CTDC also has a ball valve and strainer in the same housing.
- For all compressor sizes
- 0 to 16 bar, HP version up to 80 bar
- Simple and inexpensive
CSLV and CSLVE – compressed air savers
Closes the network when nobody needs air

Every network has leaks. The CSLV sits after the air receiver and closes the network, for example at the end of a shift, controlled via the light switch. The air stays in the receiver and the compressor runs less.
- For 1" and 2" pipes
- Fewer operating hours, less electricity
- Proven worldwide
Oil-water separator
Dispose of condensate cleanly

The oil-water separator filters the oily condensate. The oil stays in the filter and is disposed of properly, and the cleaned water can go into the sewer. For smaller systems up to 2 m³/min there is a new, particularly easy-to-maintain version.
- For systems of all sizes
- New version up to 2 m³/min
- Tool-free filter change
Frequently asked questions
What does a poor condensate drain cost?
A timed or float drain that blows off compressed air every time it opens uses a lot of electricity over the year. Zero-loss drains such as the CCNL or CMNL therefore usually pay for themselves quickly.
Can condensate go into the sewer?
Only if the oil has been separated beforehand. With oil-lubricated compressors, an oil-water separator therefore belongs in the system. We will advise you on the local requirements.
Where are condensate drains needed?
Wherever condensate collects: at the compressor, the air receiver, the dryer, the filters and at low points in the network.
Who maintains the compressor?
We do. As the CompAir partner for north-western Switzerland, we maintain and repair your system with genuine spare parts and service kits. If your compressed air supply fails, you can reach our on-call service on 062 552 00 88.

Drain condensate reliably?
Compressor, drying, filtration and condensate drainage must work together. We design the treatment for the air quality your application needs, install it and take care of service.
