Subsequently, one may also ask, what size is a standard shop vac hose?
Shop-Vac® brand hoses will measure roughly 1.25", 1.5" or 2.5". 1.25" accessories fit vacs with a 1.25" hose diameter. The hose opening is roughly the size of a golf ball. 1.5" accessories fit vacs with a 1.5" hose diameter.
Furthermore, what size is vacuum pipe? Central vacuum pipe is a different size to plumbers pipe. Vacuum pipe is 2″ diameter, whereas plumbing pipe is 50mm. The different sizes are because central vacuum systems originated in America and Canada and they use imperial measurement (inches).
Secondly, are all vacuum hoses the same size?
Vacuum hoses come in many different sizes, and they often play a part in many people's purchasing decisions when shopping for a new wet/dry or shop vacuum. Smaller diameter vacuum hoses are often more maneuverable and flexible, not to mention lighter, and for certain applications there are performance benefits.
Does a smaller hose increase suction?
As you shrink the diameter of your opening, two things occur simultaneously. Your CFM (air volume) drops and your water lift (suction power) increases. So if you want to pick up slightly larger debris and can give up a little on the effective suction area side, going to a smaller diameter hose makes sense.
