Legris has extended the range of its Transair rapid fit compressed air pipework system with the introduction of two new sizes designed especially for ring mains. The 76 and 100mm Transair pipework are available in both aluminium and stainless steel and are suitable for compressed air, vacuum (98.7%) and inert gas such as argon and nitrogen. With all major components interchangeable and reusable, the range is also compatible with the four other sizes of Transair pipework – from 63 to 16.5mm. Maximum working pressure is 16bar and working temperatures are from -20 to +60C.
