BriskSpring N1-8A-BS 40 Micron Sediment Pre-Filter with Dual Pressure Monitoring and Manual Backwash
Product Overview
The N1-8A-BS is designed for installation at the main water inlet before downstream plumbing and water equipment.
Municipal tap water passes through the 40 micron stainless steel filter mesh. The mesh helps intercept visible sediment, rust particles, pipe debris and suspended particles.
Two pressure gauges are integrated into the product structure for convenient pressure observation. The manual flushing and scraping components support routine cleaning and sediment discharge without requiring electrical power.
Key Features
40 Micron Sediment Pre-Filtration
The reusable SUS316L stainless steel filter mesh provides a listed filtration precision of 40 microns for compatible whole house water inlet applications.
Dual Pressure Monitoring
The product incorporates two pressure gauges at different positions in the assembly, allowing users to observe pressure conditions during operation.
The exact monitoring function of each gauge should be confirmed before publishing inlet and outlet pressure claims.
4 m3/h Water Flow Rate
The listed water flow rate is 4 m3/h or 17.6 GPM, supporting compatible residential and light-commercial municipal water systems.
Manual Backwash and Drainage
The product sheet lists the flushing mode as manual. The scraping components and drainage structure support removal of accumulated sediment during maintenance.
Sewage Reminder Dial
A sewage reminder dial is shown as a product feature, helping users manage routine flushing schedules.
This is a maintenance reminder function and should not be described as automatic flushing.
SUS316L Stainless Steel Mesh
The filter element uses SUS316L stainless steel for a washable and reusable sediment filtration structure.
H59-1 Brass Connector Components
The main connector material is listed as premium H59-1 brass.
Flexible Connection Options
The product is available with 3/4 inch or 1 inch connections. The final thread standard and connection configuration must be confirmed before ordering.

Working Principle
Municipal tap water enters through the brass connection assembly and passes through the 40 micron SUS316L stainless steel mesh.
Visible sediment and suspended particles are retained by the filter screen before the water continues into the downstream plumbing system.
The two pressure gauges provide visual pressure observation. During maintenance, the user operates the manual scraping and drainage structure to loosen and discharge accumulated sediment.
This product is intended for sediment pre-filtration. It is not presented as a water softener, activated carbon filter, reverse osmosis system or disinfection device.
Product Advantages
Whole House Inlet Protection
The filter can be installed before downstream plumbing, water heaters and compatible water-treatment equipment to reduce coarse sediment loading.
Pressure Observation at Two Positions
The dual gauge structure provides more pressure information than a standard single-gauge pre-filter.
Washable Filter Element
The SUS316L mesh can be cleaned and reused. Actual service life depends on water quality, operating conditions and maintenance.
Manual Operation Without Electricity
The listed flushing mode is manual, and no electrical controller is shown.
Compact Integrated Structure
The listed dimensions are 160 x 80 x 270 mm, integrating filtration, pressure observation, scraping and drainage functions into one unit.
Serviceable Component Design
The structural drawing shows separate covers, sealing components, filter bottle, filter mesh and scraping parts for inspection and maintenance.
Recommended Applications
- Whole house municipal tap water pre-filtration
- Residential main water inlet systems
- Apartments and villas
- Light-commercial water supply systems
- Upstream sediment protection for water heaters
- Upstream protection for downstream water-treatment equipment
- Plumbing and water-treatment distribution projects
Installation Guidance
Before installation, confirm:
- Required connection size
- BSPP, BSPT, NPT or other thread standard
- Male and female connection arrangement
- Water flow direction
- Available installation clearance
- Drain pipe routing
- System pressure
- Position of both pressure gauges
- Operation space for the scraping and drainage controls
Install the filter according to the supplied manual and keep the drainage section accessible for maintenance.
Maintenance Guidance
Inspect the filter regularly according to actual sediment accumulation and changes in water flow.
Maintenance frequency may depend on:
- Local water quality
- Sediment concentration
- Household water consumption
- Operating pressure
- Pressure gauge readings
- Changes in downstream flow
Use the sewage reminder dial as a maintenance scheduling aid. Operate the manual flushing and scraping components according to the confirmed instruction manual.
