Wilger Boomless Sprayer Components

Wilger manufactures a line of boomless sprayer components that can provide variable sprayer rates and swath widths for any application.

Boomless sprayers are used as utility sprayers.
For many spraying applications, traditional boom sprayers cannot reach or are unsafe to operate, so boomless sprayers provide many of the same benefits of boom sprayers without the traditional sprayer footprint.

Spraying pastures, ditches and roadways as well as any application that should be covered from a distance from the target are prime candidates for boomless spraying.

Often boomless sprayers are configured to be mounted temporarily to a vehicle or equipment for operations that do not have need for a dedicated sprayer (i.e. cities/townships)

Boomless Sprayer Benefits

Adjustable
Swath Width

Pressure release valve modules allow the user to set a max pressure level to maintain. If the pressure goes beyond the set maximum, the PRV module will open and release the excess flow to maintain the pressure below the maximum.

Swath or spray distance can be changed by adjusting pressure sprayed as well as adjusting the spray direction.

Wilger provides swath width charts to achieve ideal swaths/coverage.

Swath Direction

Wilger’s boomless sprayer use Combo-Rate® nozzle body components which can swivel 360°, so any swath or spray direction can be matched.

This is important for applications that targeting certain areas of an application with consistently more spray. (i.e. spraying weeds down the side of a highway)

Adjustable
Flow Rates

COMBO-JET® Spray Tips

Boomless sprayers use Combo-Jet® tip-caps to set the base flow rates, spray tips can be simply changed or turned off (see below) to have infinitely variable flow combinations.

Since boomless sprayers typically may have a wide range of speeds, having the ability to vary the flow rate becomes paramount to having a good application.

Compact
Manifold Assembly

A boomless nozzle assembly with 7 nozzle bodies built in.

Boomless Manifolds are modular and use very little footprint, so they can build the most versatile sprayers with the least amount of space required.

Boomless sprayer assemblies typically come stock in 3 tip to 7 tip manifolds. As all manifolds are modular, they can easily be expanded further.

Diaphragm Check Valve & Shut-off Options

Wilger's standard 10PSI diaphragm check valve. Also available in 4PSI and 15PSI options.

Diaphragm check valve

Available in 4PSI, 10PSI (standard) and 15PSI versions
Fairprene diaphragms standard. VITON® diaphragms available.
Wilger's Manual ON/OFF diaphragm check valve

Manual ON/OFF
check valve

When ‘ON’, it acts as a 10PSI* check valve.
When ‘OFF’, it turns off the flow completely to that body (*4PSI/10PSI/15PSI options are available)
Fairprene diaphragms standard. VITON® diaphragms available.
Air-Off Module for Combo-Rate Nozzle Bodies

Air-Off check valve

Acts as a standard diaphragm check valve, but when an attached air line is charged, it will turn OFF the flow to that body.
Fairprene diaphragms standard. VITON® diaphragms available.
Pressure release valve modules allow the user to set a max pressure level to maintain. If the pressure goes beyond the set maximum, the PRV module will open and release the excess flow to maintain the pressure below the maximum.

Pressure Release Valve

The pressure release module is a valuable tool for simpler sprayer systems that do not have any way regulate flow pressure.
Effectively, a release valve is manually turned until the ideal pressure maximum is set, and the excess flow will be sent through the body (and typically recirculated back into the sprayer tank).
