Micro Range Of Autovents

***NLB has developed the Micro range for the 20% of European radiators that have tappings other than 1/2” BSP***. In order to fit narrower tappings, the operating mechanism of the Micro range is contained in a canister that fits outside body of the radiator. Most radiators using such small tappings locate the tapping at the back of the radiator. Initially, NLB manufactured a “Retail” Micro with 2 adaptors which between them covered 5 tapping sizes, 1/4” BSP, 1/8” BSP, and 5, 6 and 6mm Barlo/Quinn. We also made OEM versions of the Micro with one thread machined onto the body of the Micro for manufacturers and distributors of radiator to fit as standard.
