How far should the filter basket be from the top of the stacks?
The filter basket should be at least 1.5 to 2 inches higher than the top of the velocity stacks. This is accomplished by sliding the base plate and base plate seals along the stacks until the proper position is reached. Once the base plate and seals are in the proper position, lock them down. This optimizes filter performance and keeps the vacuum created at the top of the stacks from sucking the basket and filter element downwards.
