Venturi Injector
The BLUSTAL Venturi Injector draws liquid fertilizer directly into the irrigation line using the pressure difference across it — no external pump or power needed. It is the simplest way to add fertigation to a drip or sprinkler system. Match the injector to your line size and flow rate for correct dosing. Contact BLUSTAL for sizing help and a quotation.

Pressure Gauge
The BLUSTAL Pressure Gauge lets you read the working pressure at the pump, filter or manifold so a drip or sprinkler system can be set up and monitored correctly — a rising gauge reading across a filter is the standard signal that it needs cleaning. Available in common ranges and connections. Contact BLUSTAL for options and pricing.

Venturi Injectors, Filters & Valves
Filtration, fertigation and control components that protect and run irrigation systems
BLUSTAL supplies the filtration, fertigation and control components that keep drip and sprinkler systems running — screen, sand and hydrocyclone filters, venturi injectors for fertigation, and a full range of valves (ball, solenoid, non-return and pressure-relief) with pressure gauges. Clean water and correct pressure control are what stop drippers and nozzles from clogging, so these parts are essential to any reliable irrigation layout.

Ask BLUSTAL for product guidanceFiltration matched to the water source
Screen filters suit relatively clean water, sand and media filters handle organic load and algae, and hydrocyclones remove sand, so the right choice depends on the water source.
Complete control range
Ball, solenoid, non-return and pressure-relief valves with gauges cover isolation, automation and pressure protection from one supplier.
Common applications
- Filtration ahead of drip, micro-sprinkler and fogging lines
- Fertigation dosing via venturi injectors
- Flow, isolation and pressure control on irrigation mains
- Dealer and project supply of irrigation control components
Before you request a quote
- ✓Share your water source (borewell, pond or canal), flow rate and system type so the right filter grade and size can be recommended.
- ✓State whether you need fertigation (venturi) and any automation (solenoid valves) so control parts are matched.
- ✓Ask for filter, valve and fitting compatibility with your existing mainline size.
| Structure option | Best fit | Project notes | Related components |
|---|---|---|---|
| Screen filter | Borewell / relatively clean water | Removes suspended solids down to the screen mesh; easy to clean. | Plastic or metal-body screen filters (16mm to large) |
| Sand / media filter | Ponds, canals, water with algae or organics | Traps fine organic matter a screen cannot; back-washable. | Metal-body sand filters |
| Hydrocyclone filter | Sandy borewell water | Spins out heavy sand before the main filter. | Plastic-body hydrocyclone filter |
| Venturi injector | Fertigation / chemigation | Draws fertilizer into the line using pressure differential; no external power. | Venturi injectors |
Which irrigation filter do I need?+
It depends on the water source: screen filters for relatively clean water, sand or media filters for organic load and algae, and hydrocyclones for sandy water. Share your water source so BLUSTAL can advise.
What does a venturi injector do?+
A venturi injector draws liquid fertilizer into the irrigation line using the pressure difference across it, enabling fertigation without an external pump.
Why do drip systems clog, and how do filters help?+
Drippers clog when sand, silt or organic matter passes into the line. Correct filtration at the head removes these particles and is the main safeguard against clogging.
Does BLUSTAL supply valves and pressure gauges too?+
Yes. Ball valves, solenoid valves, non-return and pressure-relief valves and pressure gauges are part of the range, so filtration and control can be sourced together.
