Intelligent Control Panel
One-touch quick setting for flushing cycle (automatic cleaning after 7, 15, or 30 days). Press the flush button to activate the intelligent cleaning mode with a single touch.
The self-cleaning pre-filter is commonly used as the first line of defense for whole-house water purification. It is usually installed near the main water inlet of the plumbing system, and can also be installed in front of water-related equipment to filter out large particle impurities such as sediment, rust, and suspended matter from tap water, protecting household water appliances from damage and extending their service life. The self-cleaning pre-filter also features an automatic filter mesh cleaning function, reducing the hassle of manual disassembly and cleaning, ensuring long-term efficient operation.
KM-PF-04 Intelligent Self-Cleaning Pre-filter
KM-PF-02 Knob Self-Cleaning Pre-filter
The KM-PF-04 intelligent self-cleaning pre-filter allows users to set flushing times through a water-electricity-separated smart touch control panel, enabling automatic backwashing. When the timer triggers a backwash operation, the system opens the drain valve, quickly lowering the water level inside the filter. This creates a pressure difference near the filter screen, forming a siphon effect. Water flows backward into the filter screen due to the siphon effect, flushing impurities out of the drain outlet. The siphon backwash utilizes the water's own weight and negative pressure difference, requiring no additional pressurizing equipment. This process is fast, uses minimal water, and effectively removes impurities.

SS316L medical grade stainless steel filter screen, corrosion-resistant, wear-resistant, high-precision filter screen, allowing it to intercept impurities such as red worms, rust, and sediment over 40 microns.
Polymer anti-freeze explosion-proof filter bottle, resistant to freezing at -30 °C, explosion-proof at 60 kg, bottle-grade material, free of Bisphenol A, ensuring healthy drinking water and stable operation.
Food-grade wiper-style matrix silicone rubber scrapers are used to remove impurities from the filter mesh while preventing the traditional brush scraper from harboring dirt and particles.
The brass head is equipped with a food-grade lead-lined layer, completely isolating the water source from the brass head to prevent the leaching of lead and other heavy metals, thus avoiding secondary water pollution.
During the flushing and drainage process, the ball valve automatically opens. After the raw water enters the filter, the water flow creates a vortex siphon effect, flushing around the filter mesh.

KM-PF-02 knob self-cleaning pre-filter controls the self-cleaning switch by manually rotating the button on the bottle. When the drain button is manually rotated to 'open,' the water flow rapidly forms a strong rotating current (vortex) under the action of centrifugal force. Larger particle impurities are flung to the outer wall of the filter cartridge by the water flow and gradually settle to the drain area at the bottom.
The inner pressure gauge is used for real-time monitoring of internal water pressure. The outer time record dial requires the pointer to be adjusted to the current month during initial installation, helping users remember the next cleaning date based on the cleaning cycle.

The drainage operation is simple. By manually rotating the drain button, the user can control the drain switch and perform cleaning operations at any time as needed.
Larger particle impurities are flung to the outer wall of the filter cartridge by the swirl, and gradually settle to the drainage area at the bottom, effectively addressing the issue of filter clogging.
