Bunnings high flow filter is a mainstream large diameter pleated security filter cartridge favored by commercial and industrial water treatment users, commonly deployed on the inlet pipeline of ultrafiltration systems. Compared with numerous small-size filter cartridges, a single bunnings high flow filter achieves remarkable water throughput, greatly simplifying the layout of filter housings, valves and connecting pipelines of ultrafiltration pretreatment stations, saving initial equipment investment and daily replacement labor cost.
Raw water firstly eliminates bulky sediment, rust and fiber impurities via upstream liquid filter, then flows into bunnings high flow filter for precision interception of micro pollutants that easily block ultrafiltration membrane pores, avoiding irreversible contamination and scratch damage on ultrafiltration membrane surfaces. We supply multiple series of compatible high flow filters to match different ultrafiltration project working conditions:
For high-purity water ultrafiltration pretreatment in electronics and pharmaceutical industry: select High-Flow Filter Cartridges: The Pinnacle of Performance in Industrial Filtration
For municipal reclaimed water reuse ultrafiltration stations: adopt High-Flow Filter Cartridges: Redefining Industrial Water Purification
For petrochemical wastewater tubular ultrafiltration front protection: use High Flow Filter Cartridge: Maximizing Efficiency in Industrial Liquid Treatment
For high turbidity raw water and corrosive wastewater ultrafiltration projects: deploy Premium High Flow Filter Cartridges – Engineered for Harsh Working Conditions
The complete structure of bunnings high flow filter includes gradient pleated filter media, integrated injection molding PP reinforced skeleton, upper and lower sealed end caps, elastic sealing rings and external anti-impact protective cage. Available filter media options: polypropylene, glass fiber and PTFE. Filtration precision covers 1μm ~ 50μm. Common interface types include 226 fin connector and flat end cap, compatible with most standard high flow filter housings on the market. All finished filters pass bubble point tightness test and hydraulic pressure resistance test before delivery, to ensure stable leak-free operation when matched with ultrafiltration equipment. Our factory provides spot supply of standard compatible models and customized service of length, precision and sealing materials for non-standard ultrafiltration projects.
The whole filtration workflow forms three-level sequential purification: liquid filter coarse filtration → bunnings high flow filter precision filtration → ultrafiltration membrane deep separation. The filter cartridge traps pollutants of different particle sizes through physical interception, adsorption and inertial sedimentation of gradient folded layers.
After preliminary coarse filtration by front liquid filter, raw water enters filter housing and permeates from outer folded layer inward to the central water collecting tube of bunnings high flow filter. Large particles are captured by outer coarse filter layer, tiny colloids and organic pollutants are locked by inner fine filter layer. Treated clean water converges and flows steadily into ultrafiltration equipment to remove bacteria, macromolecular organics and micro suspended substances. Optimized pleated structure keeps low system pressure drop under high flow, and will not cause water shortage during continuous water production of ultrafiltration units.
Pollutants keep accumulating inside filter folds as filtration proceeds, leading to gradual rise of inlet and outlet differential pressure of filter housing. When pressure difference reaches 0.25MPa warning threshold, operators should replace the filter timely. Clogged filters will increase water pump operating load, reduce ultrafiltration inflow and accelerate membrane fouling.
Water filtered by bunnings high flow filter can be directly used as backwashing water source of ultrafiltration membrane modules. Mixed with compressed air to form gas-water cleaning medium, it washes pollutants attached to membrane surface, effectively slow down ultrafiltration membrane fouling rate and extend the chemical cleaning cycle of ultrafiltration equipment.

Q1: What protection effect can bunnings high flow filter bring to ultrafiltration equipment?
A: It intercepts fine suspended pollutants in raw water, reduces pollutant load on ultrafiltration membranes, slows down membrane fouling, extends membrane service life and lowers maintenance shutdown frequency of ultrafiltration production lines.
Q2: Can you customize material, precision and size of bunnings high flow filter for our ultrafiltration system?
A: Yes. Our technical team adjusts all filter parameters based on on-site water quality, system flow and existing filter housing size to achieve perfect matching with your ultrafiltration equipment.
Q3: How long is the normal replacement cycle of standard bunnings high flow filter?
A: Under clean water environment, replacement cycle is 1.5–3 months. If raw water turbidity is high, pressure difference rises rapidly, replacement should be finished within one month.
Q4: Why install industrial liquid filter before bunnings high flow filter for ultrafiltration pretreatment?
A: Front liquid filter traps hard impurities such as gravel and rust blocks, preventing sharp particles from scratching folded filter media, delaying filter clogging speed, and forming dual protection for downstream ultrafiltration membranes.
Q5: What causes premature blockage of bunnings high flow filter during operation?
A: Excessive impurity content in inlet water, malfunction of front liquid filter, long-term overload flow operation and excessively fine selected filtration precision will lead to fast pressure difference rise and early clogging.
Q6: Can multiple bunnings high flow filters work in parallel to supply water for extra-large ultrafiltration units?
A: Fully supported. Multiple filters installed inside one large filter housing operate synchronously to provide stable ultra-large flow qualified water for heavy-duty ultrafiltration equipment, widely adopted in municipal desalination and power plant water treatment projects.
