Vertical tower press family
Replacement Cloth for Vertical Pressure / Tower Press Filters
Vertical pressure filter and tower press are the same machine under two names. This page covers replacement cloth for that family — one endless zigzag cloth threaded through the plate stack — across the OEMs listed below.
Replacement cloth fabricated to your machine dimensions. Not an OEM spare part. All OEM names are used for compatibility reference only.
How the machine works
Where the cloth sits
A vertical pressure filter — the tower press family — stacks filtration chambers one above the other and threads a single endless cloth through the whole stack in a zigzag. Cake forms in every chamber at once, the pack opens, and the cloth indexes forward to discharge and wash before the next cycle closes. Two consequences for the cloth: it is one continuous loop rather than one piece per chamber, so a single failure stops the machine, not one chamber; and it is pulled through the pack on every cycle, which makes elongation control matter more than raw breaking strength. The cloth is specified by plate size and cloth path, not by belt width.
Role of the cloth
Three things worth knowing
- One cloth, whole machine. There is no spare chamber to run on while you wait, so the replacement date is a planning decision, not a reaction.
- Elongation is the controlling property. A loop that stretches drifts out of its path and starts taking damage at the guides.
- The spec language — weave, polymer, joint, elongation — lives on the product page, not here. This page is about your machine.
Key dimensions and duty
Reference figures, and what is still open
Industry reference
Figures published by the machine makers. These are not our mill's figures, and company-stated numbers are labelled.
| Parameter | Industry reference | Basis |
|---|---|---|
| Metso Larox PF filtration area | 1.6–168 m² class | OEM published — observed |
| Roxia TP filtration area | TP60 60–168 m² tables | OEM published — observed |
| Roxia cloth cycle figure | ~6000 cycles | Company claim — not an independent survey |
| Pneumapress size range | UNKNOWN this pass | Not published in the sources we hold |
Parameters to confirm with your RFQ
Our own mill figures are not published yet. We do not print a number we have not measured, so these are confirmed in writing against your plate drawing during the engineering review.
| Parameter | Our mill |
|---|---|
| Maximum plate area we can weave for | UNKNOWN — confirmed per RFQ |
| Maximum cloth path length | UNKNOWN — confirmed per RFQ |
| Cloth weight for your duty | UNKNOWN — confirmed per RFQ |
| Air permeability range | UNKNOWN — confirmed per RFQ |
| Lead time | UNKNOWN — confirmed per RFQ |
OEM compatibility
Machine families in the vertical pressure group
3 OEM families, with the evidence level we hold on each one. Company-stated install counts and cycle figures are labelled as company claims — they are not independent surveys.
| OEM family | Typical duty | Cloth form | What we need from you | Fit status | Evidence |
|---|---|---|---|---|---|
| Metso Larox PF Published size: 1.6–168 m² class | Mining conc., chemicals, food | Endless zigzag, low elongation | Plate size / area + old cloth | Unverified | Company + OBSERVED 3rd party >1300 installs — company; zigzag single cloth Replacement open: YES |
| Roxia TP Published size: TP60 60–168 m² tables | Mining, chemicals | Endless zigzag, low elongation | Plate size / area + old cloth | Unverified | OBSERVED pages ~6000 cycles — company Replacement open: YES — they state other towers |
| Pneumapress Published size: UNKNOWN | Chemicals, minerals | Endless zigzag, low elongation | Plate size / area + old cloth | Unverified | OBSERVED compat pages US tower press family Replacement open: YES |
Brand pages publish in batches. A brand without a link here is still quoted the same way — through the engineering review.
The Metso naming trap, spelled out.
Larox PF / PF-DS is the vertical tower press on this page. Larox RT (Pannevis) is an indexing vacuum filter — a different family with different cloth mechanics — and we do not supply cloth for it. Larox RB is the rubber-belt legacy line and belongs to the horizontal vacuum belt filter family.
BHS BF — Pharma, food, sieves. Different cloth mechanics — not mapped to our belt range.
Metso Larox RT / Pannevis — Chemicals. Indexing vacuum — do not mix with Larox PF or RB.
Replacement route
How a replacement cloth gets made
Cloth for this family already comes from more than one source — the OEM and third-party weavers both supply it. That is the market we work in, and we say so rather than implying a channel we do not have.
- 1
Send the plate data and the old cloth
Plate size or filtration area, machine brand and production line, and the old cloth itself or photos of it — including how it is joined.
How to measure your old cloth → - 2
We build the loop to that path
One endless cloth for the whole stack, built to your plate dimensions and cloth path, with the low-elongation construction this family needs.
- 3
Test, pack, ship
Air permeability and tensile checks before packing, then export crating with the machine reference on the label.

move a machine up this ladder — only a real dimension package, a trial or a repeat order does.
What we need from you
Plate size / area + old cloth
- Machine brand
- Model or production line — "unknown" is an accepted answer, send the nameplate instead
- Plate size, or the filtration area
- The old cloth, or photos of it including the joint

A cloth quote without plate data is a guess. With the list on the left we can quote the cloth, or tell you we are not the right supplier for that machine.
