A label, face dimensions and frame depth are often a useful starting point. For larger or mixed estates, a site survey can create a clearer asset record.

Panel-filter questions

Useful answers before you specify

The right grade depends on the system role and the level of protection required downstream. A free site survey or the existing label, dimensions and application details help confirm the correct filter grade for your system.

Technical help without the hard sell

Send the panel-filter details you have

Dimensions, grade, quantity, site and a photograph of the existing label can help Maxi review the requirement.
