Inline Pressure Filters (BIG & TIG)
Designed for any pressurized water system — agricultural, municipal, industrial, or hydropower — delivering durable stainless-steel performance with manual or automated cleaning.
BIG Series
Blue Inline Gasketed
Versatile inline pressure filter supporting multiple cleaning technologies across all industries. Protect pumps, valves, heat exchangers, and emitters with reliable stainless-steel construction.
Cleaning Technologies:
Brush Cleaning (BIF Manual + RAB Automatic)Vacuum Cleaning (MVC Manual + AVC Automatic)BIG-S Series
Stainless Inline
Cost-optimized stainless steel inline filter with modular universal ports. Precision filtration performance in a streamlined package ideal for budget-conscious projects.
BIG-S Series DetailsValue Stainless: Premium 304 stainless construction at an accessible price point.
GNG Series
Non-Gasketed Economy
Budget-friendly inline filtration with ring-lock quick-release head and painted mild-steel body. Economical upfront cost with fast maintenance access.
GNG Series DetailsQuick-Release Head: Ring-lock design for tool-free screen removal and cleaning.
TIG Series
True Inline Gasketed
Compact inline design with quick-access end caps for manual cleaning. Ideal for space-constrained installations, municipal pre-treatment, industrial process water, and applications where true-inline flow path is required.
TIG Series DetailsCompact Design: Minimal footprint with full-flow, low head-loss configuration for tight spaces.
Suction Screens
Protect pumps and filtration equipment from large debris at the source. Available with configurations meeting NOAA/WDFW fish-screen approach-velocity and open-area criteria — approved for surface-water and dam intake use.
Standard Suction Screens
Manual Cleaning
Traditional pump intake screens with removable basket design for manual cleaning. Cost-effective protection for ponds, wells, and accessible water sources.
Learn About Standard ScreensSCS2 Self-Cleaning
Automatic Intake Protection
Self-cleaning suction screen uses pump discharge water to power internal spray nozzles. Only the internal spray bar rotates—the screen itself is stationary (no external moving parts). Automatically cleans while maintaining full flow—no external power or controls needed. Ideal for agricultural, municipal, and industrial intakes.

Fish-Friendly Intake
Wedgewire passive screens maintain <0.2 ft/sec approach velocity for fish-safe operation. Designed for hydropower intakes, dam penstock screening, and canal diversions. No moving parts—ideal for environmental compliance and low-maintenance applications.
Learn About PSFChoosing Between Self-Cleaning and Passive
Self-Cleaning (SCS2) works best with variable debris loads, when pump discharge water is available, and continuous operation is needed. Passive (PSF) is required for fish-safe regulatory compliance, low-debris environments, or when simplicity and zero power consumption are priorities.
Water Box & Specialty Filtration
Coarse intake screening and fine filtration solutions for pump stations, canal intakes, and specialty applications.
Water Box (WB)
Coarse Intake Screening
General-purpose intake screening for ponds, canals, and sumps. Large screen area removes bulk debris (leaves, twigs) before water reaches pumps and filters.
Water Box DetailsBasket with Bag (BWB)
Fine Filtration
Fine filtration using replaceable bag inserts (1-200 micron) for algae, silt, and micro-particulates. Ideal for polishing and targeted particle removal.
BWB DetailsMesh & Perforation Quick Guide
Typical starting points for common applications. Every site varies based on water quality and system design.
| Application | Typical Starting Point | Micron Range |
|---|---|---|
| Drip Irrigation | ~120 mesh | 125 µm |
| Micro-Sprinkler | ~80 mesh | 177 µm |
| Center Pivot | ~50 mesh | 297 µm |
| Intake Protection | ~30 mesh / 1/32–1/16" perf | 595 µm |
Important: Final mesh or perforation selection depends on emitter orifice size, solids loading, maintenance interval requirements, and water source characteristics. Custom sizes beyond these standards are available—contact our filtration specialist team for application-specific recommendations.
