Pentair C500 Automatic 40
Pentair C500 is an automatic 40-micron prefilter that captures sediment before carbon filters, softeners, UV, UF, or RO in homes and commercial buildings.
Short Answer
The Pentair C500 automatic prefilter is a 40-micron inlet strainer that captures sand, rust, and coarse sediment before water reaches carbon filters, softeners, UV, UF, RO, taps, and other equipment. The automatic C500-W1 model provides scheduled flushing, a transparent inspection window, and a pressure gauge for quick operating checks.
PT Watermart Perkasa, operating at water.co.id, supplies the Pentair C500 and point-of-entry components in Indonesia. Model suitability depends on simultaneous peak flow, dynamic pressure, pipe size, sediment loading, drain capacity, and the downstream equipment’s pressure requirement.
Where Is the C500 Installed?
The C500 is a point-of-entry prefilter. It is normally installed after the meter or pump and before the main treatment stages.
A typical sequence for a home, apartment, villa, or commercial property is:
- Pentair C500 for coarse sediment.
- Pentair HydraSmart carbon filtration for colour, taste, odour, and residual chlorine where required.
- A HydraSmart softener when testing confirms excessive hardness.
- A point-of-use drinking-water filter or under-sink RO system at drinking points.
Pentair C500-W1 Specifications
| Parameter | Nominal value in Pentair product material |
|---|---|
| Model | C500-W1 automatic |
| Filtration precision | 40 microns |
| Clean-water flow | 6.5 m³/h |
| Operating pressure | 0.1-1.0 MPa |
| Dimensions | 124 × 109 × 323 mm |
| Listed inlet-water quality | Municipal tap water |
| Flushing | Scheduled automatic flushing; battery and USB Type-C power |
These specifications come from the Pentair product material supplied to Watermart. Confirm the current model, connections, pressure rating, and availability when requesting a quotation.
Is the Nominal 6.5 m³/h Flow Sufficient?
Compare the nominal 6.5 m³/h flow with building peak demand, not average daily use. Add the outlets that can operate simultaneously, then check dynamic pressure at the installation point and the minimum pressure required downstream. Allow for flushing without causing essential services to lose pressure.
| Site information | Decision it affects |
|---|---|
| Simultaneous peak flow | Whether one C500 is sufficient or the building needs zones |
| Static and dynamic pressure | Pressure available after the prefilter and downstream stages |
| Pipe size and direction | Connections, installation clearance, and system pressure loss |
| Sediment loading | Initial inspection frequency and flushing schedule |
| Drain capacity | Disposal of flushing water without ponding or backflow |
Measure flow and pressure again during commissioning. If peak demand approaches the nominal limit, request a hydraulic review of the full treatment train, including any carbon filter, softener, UV, UF, or RO downstream of the C500.
Operating Benefits
- Reduces coarse sediment loading on cartridges and downstream treatment stages.
- Can extend downstream filter service intervals when feedwater and sizing match the design.
- Automatic flushing reduces routine housing disassembly.
- The pressure gauge and inspection window support quick operator checks.
- Flexible connection orientation helps accommodate existing pipework.
What the C500 Does Not Do
The C500 does not replace carbon filtration, softening, disinfection, UF, or RO. A 40-micron strainer is not intended to remove dissolved salts, hardness, dissolved taste and odour compounds, or guarantee microbiological safety. System selection must still begin with feedwater quality, peak flow, pressure, and the required treated-water quality.
Provide a suitable drain for flushing and keep the installation within its permitted pressure range. Well water, rainwater, and surface water can need additional pretreatment because they differ from municipal supply.
Pentair C500 FAQ
Who supplies the Pentair C500 in Indonesia?
PT Watermart Perkasa supplies the Pentair C500 through water.co.id for inlet lines serving homes, apartments, villas, hotels, and commercial buildings. Confirm the model, connections, inlet conditions, service clearance, and flow capacity before procurement.
Does a 40-micron strainer replace a fine cartridge?
No. The C500 captures coarse sediment and helps protect downstream stages. A finer cartridge, carbon filter, softener, UV, UF, or RO stage is still selected from water-test results and the required treated-water quality.
What determines whether one C500 is sufficient?
Use simultaneous peak flow, static and dynamic pressure, pipe size, sediment loading, downstream pressure requirements, and available drain capacity during flushing. Verify flow and total treatment-train pressure loss during commissioning.
Information for a Quotation
Send the water-test results, source, normal and peak flow, pressure, pipe size, installation space, and existing treatment train to Watermart. We will check whether the C500 should operate alone or as part of a Pentair point-of-entry and point-of-use system.
