Simply stated there is no equal. Big-Lock from Gardner Denver has taken large diameter piping systems to a new level. Ten times lighter than steel, without compromising any structural strength, the system is easier to install than plastic and delivers a quality of air, gas or vacuum that is equal to that of high cost welded stainless steel systems. The secret of the Big-Lock system is twofold. First is the tubing design. Big-Lock is manufactured from marine-grade aluminium that affords it the highest level of protection against contamination. This ensures that the media travelling through a system encounters very little turbulence, while enabling high flow rates with minimal pressure losses compared to conventional steel systems.
