THE SPECIFICATION ENGINE

We match what standard catalogues miss.

A part number is a starting point. The right match also considers the fluid, the equipment and the way your facility operates.

Right specification

Match the media to the fluid, particulate load and operating conditions, with the product sheet as the starting point.

Media and fluid compatibility
Material-specific micron options
Temperature limits and application review

Right fitment

Check the dimensions that a part number can leave out, from the bag collar and seam to the width and core of a roll.

Size 1 and Size 2 bag dimensions
Plastic, steel or stainless steel rings
Roll width, core fit and custom-cut options

Right supply cadence

Share your usage, order quantity and delivery location so availability and replenishment can be discussed before ordering.

OPERATIONAL REALITY

Less guesswork at the next changeout.

Build a clearer purchasing specification before an urgent replacement becomes an uncertain order.

AD-HOC REORDERING

When details are left unchecked

–
Fitment uncertainty
A similar-looking ring or roll may have different dimensions.
–
Unclear media selection
A familiar product code may not reflect the current fluid or operating conditions.
–
Conflicting specifications
Different micron values can appear in the same supplier document.
–
Last-minute purchasing
An urgent order leaves less time to confirm availability and delivery.

Open questions can carry through to the shop floor.

KATHRA TECHNICAL MATCHING

Start with a complete requirement

Check the physical fit
Record the bag size, ring and seam, or the roll width and core diameter.
Discuss the application
Provide the fluid, temperature and filtration objective for review.
Resolve differences before ordering
Clarify the material, rating and ordering code against the supplier data.
Plan the next replenishment
Share quantity, usage and delivery location to discuss supply timing.

A clearer basis for selection, quotation and ordering.

APPLICATION MATRIX

Know what you are comparing.

Use these checks to evaluate a filtration enquiry, wherever you currently source your consumables.

Evaluation criteria	An unchecked order	KATHRA specification-led approach
Specification	Reorder from a partial code.	Confirm the media, rating and complete ordering code.
Fitment	Assume a familiar size will fit.	Check dimensions, collar, seam or roll core against the equipment.
Operating conditions	Carry over the previous selection.	Review the fluid, temperature and application requirements.
Technical evidence	Treat a nominal rating as a guarantee.	Request the relevant product data and resolve discrepancies.
Supply planning	Wait until the last bag or roll.	Share usage and delivery needs; confirm lead time and availability.
