Our “QUICK BOLTS” system allows for an easy, quick and efficient way to inspect and perform any maintenance operation on the filter.
It is composed of:

• A support, which is also the cover’s point of stop, that preserves the sealing gasket from
  unintentional cuts or damage that might be caused by an excessive strength during the closure.
• A rotating part that, after being loosened, remains attached to the support, ready for closure. This
  rotating part can be supplied with eye-bolts or with bolt & nut upon request.
