Davey CrystalClear ER (2026+) Cartridge Filters - 135ft², 180ft², 225ft² and 270ft² - is backordered and will ship as soon as it is back in stock.
Davey CrystalClear cartridge filters are a water-saving, low-maintenance filtration option for pools and spas where you want clear water without the mess and water waste of backwashing.
We keep these physically in stock for fast shipping or local pick-up, unlike most drop-shipping websites.
If you are replacing an older AstralPool ZX cartridge filter, Davey CrystalClear, Davey EasyClear, or most other cartridge filters, the Davey CrystalClear ER range is often the closest current alternative by size class, filtration area, and flow rate. These filters are ideal where backwashing is not practical, where water may be scarce, or where a simple cartridge filter is preferred.
The Davey CrystalClear range is available in 135ft², 180ft², 225ft² and 270ft² models, with a solid one-piece polypropylene tank, reusable polyester cartridges, a pressure gauge, manual air bleed, and 50mm quick connect barrel unions supplied for installation.
Why People Replace AstralPool ZX Filters With Davey CrystalClear ER
AstralPool ZX cartridge filters were a compact, low-height cartridge filter range widely used on Australian pools and spas. The closest Davey CrystalClear crossover is generally:
- AstralPool ZX 100 = Davey DCC135
- AstralPool ZX 150 = Davey DCC180
- AstralPool ZX 200 = Davey DCC225
- AstralPool ZX 250 = Davey DCC270
These are the closest corresponding sizes, not guaranteed drop-in replacements. Always compare dimensions, pipe layout, union style, and the clearance needed above the filter to remove the cartridge element.

AstralPool ZX vs Davey CrystalClear Comparison
| AstralPool ZX Model | Davey Equivalent | ZX Filter Area | Davey Filter Area | ZX Max Flow | Davey Max Flow | ZX Height | Davey Main Height / Clearance |
|---|---|---|---|---|---|---|---|
| ZX 100 | DCC135 | 9.4m² | 12.5m² | 375 lpm | 381 lpm | 710mm | C: 668mm, D: 1000mm clearance |
| ZX 150 | DCC180 | 14.0m² | 16.7m² | 445 lpm | 450 lpm | 710mm | Same DCC135 / DCC180 body family |
| ZX 200 | DCC225 | 19.0m² | 20.9m² | 490 lpm | 480 lpm | 910mm | C: 811.5mm, D: 1600mm clearance |
| ZX 250 | DCC270 | 24.0m² | 25.1m² | 515 lpm | 510 lpm | 910mm | C: 941.5mm, D: 1600mm clearance |
Important: On the Davey drawings, the D dimension is the minimum clearance height required to remove the cartridge. This is especially important if the filter sits under a deck, under roofing, or in a tight plant room.

In plumbing, named sizes are not the actual measurements. A pipe called “50mm” or “2"” does not measure 50 mm across. Instead, it follows nominal sizing, an internationally-standardised naming system.
Use the Outside Diameter (OD) to check your pipe against fittings. Below is a quick reference for common spa & pool pipe sizes:
| Imperial Name | Metric Name | Pipe Diameter (OD) |
|---|---|---|
| 1/2" | 15mm | ~21.2–21.5 mm |
| 3/4" | 20mm | ~26.6–26.9 mm |
| 1" | 25 mm | ~33.4–33.7 mm |
| 1.5" | 40 mm | ~48.1–48.4 mm |
| 2" | 50 mm | ~60.2–60.8 mm |
| 2.5" | 65 mm | ~75.2–75.5 mm |
These are nominal sizes and are designed to fit matching fittings — not to measure exactly what their name suggests. These are based on PVC Pressure Pipe AS/NZ 1477 Dimensions1.
- º Internal diameters vary slightly by manufacturer and class.
- 1 Not all pool/spa fittings match these dimensions exactly. Some do not follow Australian or international standards. Chinese spas may use proprietary fittings.
Understanding Plumbing Sizes & Nominal Measurements
Plumbing sizes can be confusing. PVC and many other pipe systems use nominal sizes—the size is a name, not the exact measured dimension. This convention is used across most pool and spa systems so that pipes and fittings remain compatible.
Why pipe sizes don’t match the measurements
The Nominal Pipe Size (NPS) system standardises pipe dimensions so that pipes, fittings, valves, and accessories interoperate. Plumbers work with these nominal names every day, but DIYers can be tripped up if they try to match by a tape-measure alone.
How to Measure Pipe Correctly
-
Pipe size is identified by:
- The pipe’s Outside Diameter (OD).
- The fitting’s Inside Diameter (ID) (socket opening).
- Pipe Class / Schedule (e.g., Class 9, 12, 18 or Sch 40) relates to wall thickness and therefore the Internal Diameter (ID) and pressure rating.
- The outside diameter of a fitting is not useful (wall thickness varies by manufacturer).
Hose & Tube Dimensions
Common flexible hose sizes used in pool/spa systems (approximate IDs).
| Imperial Name | Metric Name | Inside Diameter (ID) |
|---|---|---|
| 3/8" | 9–10 mm | ~9 mm |
| 3/4" | 19 mm | ~19 mm |
BSP – British Standard Pipe Thread Sizes
BSP thread names are also nominal. The thread OD will not equal the nominal name.
| BSP Thread Size Naming | Outside Diameter (mm / inch) | TPI |
|---|---|---|
| 1/16" BSP | 7.7 mm / 0.304" | 28 |
| 1/8" BSP | 9.7 mm / 0.383" | 28 |
| 1/4" BSP | 13.16 mm / 0.518" | 19 |
| 3/8" BSP | 16.66 mm / 0.656" | 19 |
| 1/2" BSP / 15 mm | 20.99 mm / 0.825" | 14 |
| 5/8" BSP | 22.99 mm / 0.902" | 14 |
| 3/4" BSP / 20 mm | 26.44 mm / 1.041" | 14 |
| 7/8" BSP | 30.20 mm / 1.189" | 14 |
| 1" BSP / 25 mm | 33.25 mm / 1.309" | 11 |
| 1-1/4" BSP | 41.91 mm / 1.650" | 11 |
| 1-1/2" BSP / 40 mm | 47.80 mm / 1.882" | 11 |
| 2" BSP / 50 mm | 59.61 mm / 2.347" | 11 |
| 2-1/4" BSP | 65.71 mm / 2.587" | 11 |
| 2-1/2" BSP | 75.18 mm / 2.960" | 11 |
| 3" BSP | 87.88 mm / 3.460" | 11 |
