Code: MDR2/11

Product detailed description
Single-phase Condor for motors up to 2.2 kW. It differs from its sibling MDR 1 in two ways: it comes set to 6.0 to 8.0 bar instead of 8 to 10, and its connection block has a 1/4" port instead of 3/8".
Lower pressure and narrower port
The factory setting of 6.0 to 8.0 bar suits smaller workshop and hobby compressors, which don't run at higher pressure anyway. The pressure can be changed within the switch's range using the screws under the cover.
The inlet thread of 1/4" is narrower than on the MDR 1. When replacing an old switch, keep this in mind — you won't be able to screw this unit onto a 3/8" outlet without a reducer.
What is in the box
- Protection IP 44 — against objects over 1 mm and splashing water.
- Mechanical life over half a million operations, at most 120 operations an hour.
- Rotary knob for switching on and off by hand.
- Air temperature −5 to +80 °C.
- Switching capacity of 2.2 kW at 230 V according to EN 60947.
- Connection 1/4" + 3× 1/4" — one inlet and three outlets on a single block.
- Factory-set to 6.0–8.0 bar, adjustable using screws under the cover.
How it differs from its siblings
The more powerful single-phase Condor with a 3/8" inlet and pressure relief valve is the MDR1/11. Simpler 230 V versions are the TS220 and BW-0002. You'll find the full overview in the category overview.
Ventilek advises
A quarter-inch inlet versus a three-eighths-inch one — it looks like a detail, but without a reducer it won't fit.
Technical data correspond to the manufacturer's datasheet and the supplier's catalogue. The switch must be connected by a person with the appropriate electrical qualification. The pressure is set under pressure and with the electrical supply disconnected.

Condor: German precision in pressure control since 1893
In the world of compressors and pumps, the Condor brand is a byword for uncompromising quality, safety and technical excellence. As the inventor of the automatic pressure switch, this German family business with more than 130 years of tradition has grown into the world leader in its field.
History and innovation
The company was founded in 1893 by August Frede. Although it started out making centrifuges and milking machines, the decisive turning point came in 1935, when Condor was granted the world's first patent for an automatic diaphragm switch for pumps. That moment defined the brand's course as a pioneer in pressure control.
Why choose Condor components?
Condor pressure switches (above all the legendary MDR series) are now the standard relied on by respected compressor manufacturers all over the world.
- Extreme service life: Condor products undergo demanding tests (salt spray or water hammer tests, for example) that confirm their exceptional durability.
- Safety and certification: Production takes place in Germany to the strictest standards. Condor holds ISO 9001 certification and numerous international approvals, including versions for explosive atmospheres (ATEX).
- A wide range of uses: From small single-phase compressors (the MDR-1 and MDR-2 series) to powerful industrial machines that require motor overcurrent protection (MDR-3, MDR-5).
A legend called MDR
The MDR name has been on the market for more than 80 years. These switches stand out for their rugged design, high switching accuracy and the option of setting the cut-in and cut-out pressure individually. Thanks to integrated unloader valves they also let the electric motor start easily, with no back pressure.
If you are looking for the best that German engineering has to offer for your compressor or air line, Condor is a safe bet that will repay you with trouble-free operation for many years.
