6.4 Recommended spare parts/accessories

Available spare parts and accessories can be found on our compressor selection tool under
vap.bock.de as well as at bockshop.bock.de.
Only use genuine Bock spare parts!

6.5 Integrated decompression valve

The valve is maintenance free.
However, constant leakage can occur after blowing off due to abnormal operating conditions. This
leads to reduced performance and increases the compressed gas temperature. In this case check the
valve and replace as necessary.
