Part 2....

With over 75 years in the filtration industry, Baldwin Filters recognises that there is specific terminology we all use to communication different aspects related back to filters, filter maintenance and performance, filter components etc. In order to help us all understand the different characteristics of filters, regardless of the brand, we have created a series of Tech Tips where we will look at and explain the different terminology we all use

Baseplate (Tapping Plate)
Typically made of steel or aluminium, this part is threaded to attach the spin-on filter to the filter adapter and to allow fluid to exit the filter. It also includes punched holes to allow fluid to enter the filter.

Seaming Lid
This part joins the canister to the baseplate on a spin-on filter and in some cases holds the sealing gasket in place.

Sealing Gasket
The sealing gasket seals the filter to the filter adapter or to the housing sealing surface. This gasket may or may not be attached to the filter.

Canister
This is the outer shell of a spin-on filter. The canister retains all of the filter components in one unit for ease of installation and removal.

Centertube
This is typically a perforated or louvered tube which forms the centre of a filter element to support the media and through which the cleansed fluid returns to the machine.

End Cap
Plastic, metal, paper or a combination, formed to seal the two ends of a filter cartridge or element. Sealing compound is commonly placed in the end caps first, then the media is inserted into the compound. In some instances, the media is directly embedded to the end cap itself.

Media
In various forms, including cellulose, synthetic and blended materials, removes harmful contaminants from the air or fluid.

Compression Spring
This device holds the filter element in position inside the filter housing or canister. Some designs use a coil spring, while others use a leaf spring.
