Why the need for this change?
Since many of our customers have air quality and air volume issues we have decided to change to 40mm cylinders. These new cylinders will not only have the same hole spacing for installation as the 30mm cylinders but the new shafts will fit in either the new 40mm cylinders or the old 30mm cylinders so there is no need for us to carry more inventory.
These new 40mm cylinders require less air pressure to activate than the 30mm cylinders but also have a larger bumper (pad) for better brick surface contact. This bumper (pad) can be either articulating or fixed.
