Pall Ultipleat High Flow Replacement Option, PHFL Series

Plants do not replace a Pall Ultipleat because it stopped working. They replace it because a sole-sourced consumable on a twelve-week lead time is a risk the maintenance budget cannot absorb, and because twenty elements on a six-week cycle is a number that compounds.

The PHFL is a dimensional equivalent — it matches Ultipleat housing dimensions, and performance still requires a fit check and validation. Same 6" (152.4 mm) format, same 20", 40" and 60" lengths, single open end, no housing modification. It is available in three media covering working temperatures from 82 °C to 121 °C, in grades from 0.1 to 100 µm, at 50 to 200 GPM per element.

Key Features

• Housing format — 6" (152.4 mm) OD with a single open end (SOE), built to Ultipleat High Flow housing dimensions; fit in your housing is confirmed by fit check.
• Length options — 20", 40" and 60".
• Media — deep pleated or melt polypropylene (PP), glass fiber (GF) or polyester (PET).
• Grade and flow — 0.1–100 µm at 50–200 GPM per element.
• Rated limits — max. differential pressure 3.44 bar at 82°C (PP), 121°C (GF) and 120°C (PET).
• Seals — silicone, NBR, Viton or EPDM O-rings.

Applications

• Municipal and industrial water: high flow prefiltration.
• RO pre-treatment: membrane protection at scale.
• Hot process streams: glass fiber media to 121 °C.
• Cooling and process loops: side-stream filtration.

Media and Temperature Ceilings

Decide the media before the grade. The spread in working temperature is wide enough that it eliminates options rather than merely ranking them.

All three carry the same 3.44 bar differential pressure rating at their respective ceilings, and all three cover 0.1 to 100 µm.

Cross-Reference Checklist

The same housing accepts several core and adaptor variants, and the printed part number does not always distinguish them. Six items produce a same-day quote:

• Part number printed on the existing cartridge
• Housing manufacturer and model, if known
• Element length — 20", 40" or 60"
• Micron grade in service
• Fluid, working temperature and flow rate per element
• Change-out interval you are getting today

A photograph of the element’s open end and adaptor settles most of this in one go.

Qualification

Every element is tested in Pullner’s own laboratory, raw material through finished goods, on a bench including a PMI pore size analyzer, an SEM resolving to 3 nm, ICP-MS, an ion chromatograph and an IFTS single-pass rig.

For a second-source approval that documentation is normally the deciding artefact rather than the sample itself. Ask for it with the sample, not after — it removes a full cycle from the qualification. Most alternative suppliers cannot produce comparable records.

Up to two samples ship worldwide free of charge, with freight paid by the customer.

Who it is for

Plant O&M teams, system integrators and EPC contractors running Pall Ultipleat High Flow housings on industrial water, RO pre-treatment, or process and cooling loops, who want a second-source candidate for a recurring consumable.

Typical operating conditions

• Flow: 50–200 GPM per element
• Micron rating: 0.1–100 µm
• Max. temperature: PP 82°C · GF 121°C · PET 120°C
• Max. differential pressure: 3.44 bar at each media's temperature limit
• Format: 6" (152.4 mm) OD · 20", 40" or 60" · single open end
• Seals: silicone, NBR, Viton, EPDM

Recommended Pullner product family

PHFL series, part of Pullner high flow filter cartridges. Choose media on temperature first: PP for ambient and warm water, glass fiber or polyester above 82°C. Minimum order is 4 pieces; lead time is 10 working days.

What to send before quotation or sample

• Fluid / media
• Flow rate
• Micron rating
• Temperature
• Pressure
• Existing housing or current model (the Pall part number printed on the element, plus a photo of the open end and adaptor)
• Maintenance / change-out cycle
• Validation requirement

What validation is required before switching

• Fit check — engineering compares your part number, housing model, element length and a photo of the open end and adaptor against the Pullner format.
• Sample — a sample element is installed in your housing to confirm seating and seal before any order.
• Performance trial — the sample runs on your own duty while you log differential pressure, downstream quality and change-out interval against the element you use today. Scale the order only after that.

What Pullner will not claim without evidence

• Dimensional fit only: the PHFL matches Ultipleat High Flow housing dimensions, confirmed for your housing by fit check.
• No claim of matching grade or performance parity with Pall elements.
• No claim that the PHFL is approved, endorsed or supplied by Pall.
• Retention, flow and service life on your duty are confirmed by your own trial, not assumed.

Can the PHFL replace my Pall Ultipleat High Flow cartridge?

It is a replacement option for Ultipleat High Flow housings that take a 6" (152.4 mm) single-open-end element in 20", 40" or 60" lengths. Fit in your housing is confirmed by a fit check on your part number, housing model and a photo of the open end, then by a sample.

How is it validated before switching?

Validation is a fit check against your current part number and housing, a sample installed to confirm seating and seal, and a trial on your own duty. Log differential pressure, downstream quality and change-out interval against your current element, then scale the order.

What data or documentation is available?

The full specification is published on this page: media, micron rating, diameter, lengths, end cap, seals, flow, differential pressure and temperature limits. Pullner manufactures under ISO 9001. Tell engineering which documents your supplier approval needs and request them with the sample.

What are the temperature, pressure and chemistry limits?

PP media is rated to 82°C, glass fiber to 121°C and polyester to 120°C, each at a maximum differential pressure of 3.44 bar. Flow is 50–200 GPM per element. Chemical compatibility is reviewed against your fluid, including the seal choice of silicone, NBR, Viton or EPDM.

Is the PHFL an Ultipleat filter element?

No. Ultipleat is a Pall product line. The PHFL is a Pullner-made element built to the same housing dimensions: 6" (152.4 mm) OD, single open end, 20", 40" or 60" long. How it performs on your duty is confirmed by fit check and trial.
