Hydropro Filter Cartridges: Sizes, Micron & Housings
Hydropro filter cartridges from PT Watermart Perkasa: spun polypropylene 10-40 inch in 1-53 micron, Big Blue 20 inch, and 40/60 inch high-flow. Selection table and housings.
Hydropro filter cartridges are sediment elements supplied in Indonesia by PT Watermart Perkasa in two constructions: coreless spun polypropylene with a 2.38-inch diameter (10, 20, 30 and 40 inch lengths, 1 to 53 micron, plus a 4.50 x 20 inch Big Blue) and pleated meltblown high-flow cartridges in 40 or 60 inch lengths. Choose by housing length and diameter, micron rating, flow and allowable differential pressure.

Which Hydropro cartridge constructions are available?
The Hydropro line on water.co.id has two constructions. Both are 100% polypropylene, but the media form, flow direction and housing differ.
| Construction | Media form | Listed sizes | Micron ratings | Maximum operating temperature | Typical duty |
|---|---|---|---|---|---|
| Hydropro Industrial Series (spun polypropylene) | Coreless layered polypropylene fibres that hold particles through the media depth | 2.38 in. (62 mm) diameter; 10, 20, 30, 40 in. long | 1, 3, 5, 10 (all lengths); 20, 25, 53 (40 in.) | 62.8°C (range 4.4–62.8°C) | RO prefiltration, drinking-water sediment filtration, industrial process water |
| Hydropro Big Blue BB H5-20 (spun polypropylene) | Same, large diameter | 4.50 x 20 in. (114.3 x 508 mm) | 5 | 62.8°C | 20-inch Big Blue housings with more flow per element |
| Hydropro High Flow | Radial pleats of meltblown polypropylene microfibre; single open end, inside-to-outside flow | 40 and 60 in.; 76.2 mm inner and 165 mm outer diameter | 1, 5, 10, 20, 40, 70, 100 | 80°C | High flows with fewer elements, such as industrial RO prefiltration |
String-wound and pleated polyester cartridges are not part of the Hydropro line on this page; for those, see Pentair Pentek (WP Series string-wound, R Series pleated polyester). For another high-flow brand, see Pentair AquaLine.
Which sizes and micron ratings exist? Hydropro selection table
Industrial Series model codes read H[micron]-[length in inches], for example H5-40 = 5 micron, 40 inch. The exception is H35-40, which has a 53 micron nominal rating in the technical table.
| Nominal rating | 10 in. | 20 in. | 30 in. | 40 in. |
|---|---|---|---|---|
| 1 micron | H1-10 | H1-20 | H1-30 | H1-40 |
| 3 micron | H3-10 | H3-20 | H3-30 | H3-40 |
| 5 micron | H5-10 | H5-20 | H5-30 | H5-40 |
| 10 micron | H10-10 | H10-20 | H10-30 | H10-40 |
| 20 micron | – | – | – | H20-40 |
| 25 micron | – | – | – | H25-40 |
| 53 micron | – | – | – | H35-40 |
| 5 micron, 4.50 in. Big Blue | – | BB H5-20 | – | – |
All Industrial Series models have a maximum diameter of 2.38 in. (62 mm); 10/20/30/40 in. equals 254/508/762/1016 mm. Hydropro High Flow comes in 40 and 60 in. lengths in 1, 5, 10, 20, 40, 70 and 100 micron. Sources: Hydropro Industrial Series technical sheet and Hydropro High Flow brochure.
How do you choose the micron rating?
Choose the rating from the particle target and the next stage, not the smallest number. A rating that is too fine for a heavy sediment load makes differential pressure rise quickly and shortens cartridge life. In staged filtration, coarser ratings normally sit ahead of finer ones. See also 5 micron vs 1 micron cartridge filters before fixing the rating for an RO prefilter.
Which housings fit Hydropro cartridges?
The cartridge must match the diameter, length, end type and seal inside the housing. The same nominal length does not guarantee a fit.
| Hydropro cartridge | Matching housing | Check before buying |
|---|---|---|
| Industrial Series 2.38 in., 10–40 in. | Standard 10, 20, 30 or 40 in. housings for standard-diameter cartridges | Actual length, diameter, how the element is located and sealed, elements per housing |
| BB H5-20 | 20-inch Big Blue housing | 4.50 in. diameter and 20 in. length |
| High Flow 40/60 in. | A housing designed for single-open-end, inside-to-outside high-flow cartridges | 165 mm outer and 76.2 mm inner diameter, gasket/O-ring material (Buna-N or silicone), 40 or 60 in. length |
To select or replace a housing, use the cartridge housing guide and size element quantities with the cartridge and housing calculator. The industrial cartridge filter page compares Hydropro with AquaLine and Pentek.
When should a Hydropro cartridge be replaced?
Set the change-out point from differential pressure (inlet minus outlet pressure across the housing), not from the calendar alone. Record the differential pressure of a new cartridge as the baseline.
| Sign | What it means | Action |
|---|---|---|
| Differential pressure approaches the set limit | The media is loaded with particles | Replace; for Hydropro High Flow the brochure suggests replacement at 2.5 kg/cm² and a maximum of 3.5 kg/cm² at 30°C |
| Outlet flow drops at the same pump pressure | Flow is restricted by retained solids | Check differential pressure and replace when it nears the limit |
| Turbidity or visible particles at the outlet | The element may be unseated, damaged or the wrong rating | Check element position, O-rings and rating before replacing |
| Very frequent change-outs | Sediment load is too high for one stage | Add a coarser stage or a backwashable media filter ahead of the cartridges |
| Long standstill or odour | Risk of microbial growth on a wet element | Replace the cartridge and sanitise the housing to the system procedure |
The Hydropro technical sheet also warns not to use the cartridges on microbiologically unsafe water or water of unknown quality without adequate disinfection before or after the system.
What should you send for a Hydropro cartridge quote?
- Model code or a photo of the old cartridge label (for example H5-40, BB H5-20 or 60-inch high-flow).
- Element length and diameter, a housing photo and the number of elements per housing.
- Normal and peak flow, working pressure and water temperature.
- Target micron rating and the next stage (for example RO membranes).
- Current change-out frequency and the differential pressure at change-out.
- Monthly or project quantity and delivery location.
Send the data through the Watermart contact page. Stock and delivery time are confirmed with the quotation.
FAQ about Hydropro cartridges
What is the difference between Hydropro Industrial Series and Hydropro High Flow?
Industrial Series is a coreless spun polypropylene cartridge with a 2.38 in. diameter for standard 10–40 in. housings. High Flow is a pleated meltblown cartridge with a 165 mm outer diameter, 40 or 60 in. long, with inside-to-outside flow. High Flow is used when a large flow should be handled by fewer elements.
Does a 40-inch Hydropro cartridge fit another brand’s 40-inch housing?
Not necessarily. Match the 2.38 in. diameter, the 1016 mm actual length, how the element seals in the housing and the number of elements per housing. Photos of the housing and old cartridge help avoid the wrong size.
Which micron rating should an RO prefilter use?
Hydropro comes in 1, 3, 5 and 10 micron in all standard lengths, and 20, 25 and 53 micron in 40 in. The right rating follows the RO system design, the sediment load and the upstream filtration; this page does not set one rating for every system.
What is the maximum temperature of Hydropro cartridges?
Industrial Series is listed for 40–145°F (4.4–62.8°C). Hydropro High Flow is listed for a maximum operating temperature of 80°C.
Who supplies Hydropro cartridges in Indonesia?
PT Watermart Perkasa supplies Hydropro cartridges through water.co.id for industrial and commercial water treatment in Indonesia. To choose a model, send the old cartridge code, housing size, flow and micron target through the contact page.
