Holm Filters Numbering System

Holm Address

Identifying your ideal Holm filter

Here at Holm, we have a unique approach to filter identification, our standardised part numbering system for our Holm brand filters makes it easy to identify the correct filter for your application and equipment. 

All Holm filters are coded with a number that includes the filter type, the variation (effectively how it works to aid selection), and the filter manufacturer. This translates as the following format: Type|Variation|Unique Number|Manufacturer

For example: A|10|123|HOL is an Air filter that is a Spin On and is Holm branded.

The lists of references are:

> TYPE NUMBER

> VARIATION NUMBER

> MANUFACTURER

In addition to individual filters, which can be easily identified using our Filter Finder, we also offer service kits containing all the filters and accessories you need for an interim or full service on each piece of your equipment.
