High Temperature High Flow Filter Element, PHFLH Series

Hot water and hot process liquid lines are hard on standard cartridges: media softens, pleats deform and flow channels through the element. The PHFLH is a high-flow element built from high-temperature media for continuous hot-liquid service, so one element carries a large share of the line's flow.

Two media are offered. Glass fiber is rated to 121°C and polyester to 120°C, each with a maximum differential pressure of 3.44 bar at that temperature. Micron ratings run from 0.1 µm to 100 µm. The element has a 6" (152.4 mm) outside diameter, a single open end (SOE) and 20", 40" or 60" lengths, with a flow rate of 50–200 GPM. Seals are offered in Silicone, NBR, Viton or EPDM. Confirm the seal against the fluid at operating temperature, because the seal can set a lower limit than the media.

The PHFLH sits in Pullner's عنصر فلتر مياه بدرجة حرارة عالية range. For high-flow duty at ambient temperature, see the خرطوشة فلتر التدفق العالي range. It is for liquid service only. Send the fluid, flow, temperature and current model, and Pullner engineering will confirm media, micron grade, length and seal before quoting.

Can the PHFLH replace the high flow element in our hot-water housing?

It can be reviewed as a replacement option. The PHFLH has a 6" (152.4 mm) outside diameter, a single open end and 20", 40" or 60" lengths. Send the current element model and housing details, and Pullner confirms dimensional fit before recommending a change.

How is it validated before switching?

Validation runs in three steps: a fit check against your housing and current element, a sample on your own line, and a performance trial under your operating conditions. Pullner does not claim performance parity with an incumbent element until that trial data exists, and a switch is recommended only after the trial.

What data or documentation is available?

The published specification on this page covers micron rating, media, diameter, length, end cap, seals, flow, differential pressure and temperature. Elements are made under an ISO 9001 quality management system. Ask engineering for any further documentation your validation procedure requires.

What are the temperature and pressure limits?

Glass fiber is rated to 121°C and polyester to 120°C, each with a maximum differential pressure of 3.44 bar at that temperature. The PHFLH is for liquid service only. The seal can limit the stage below the media rating, so confirm it against your fluid.

What is a large flux filter?

In this range, "large flux" means high flow per element. The PHFLH handles 50–200 GPM through a 6" (152.4 mm) outside-diameter element, in 20", 40" or 60" lengths, for hot water and hot process liquids.

What is the minimum order and lead time?

The minimum order is 4 pieces and the lead time is 10 working days. Send the fluid, flow and temperature so the quote reflects the right media, micron grade, length and seal.
