Andy Guest 3 Series Jetting Machine Technical Data
Emissions-Compliant water jetting machine
Powered by a 37HP Vanguard EFI V-Twin Petrol Engine with a triplex high-pressure pump, the 3-Series now features a closed-loop EFI system for smoother starts, faster load response, and up to 25% better fuel efficiency. An Engine Control Module continuously adjusts fuel and spark delivery, while Electronic Throttle Control maintains consistent power under varying loads. The updated torque curve boosts performance, and the engine management system supports diagnostics and remapping when needed.
Upgraded Jetter Functionality & Diagnostics
The 3-Series includes several key upgrades designed to improve reliability, serviceability, and overall performance. A redesigned wiring loom, developed in collaboration with a control and automation specialist, reduces the number of connectors. This minimises potential faults, simplifies diagnostics, and improves integration with the jetter’s control panel.
The control panel itself has been upgraded to include an engine fault indicator and a new diagnostic input. These additions give service teams better visibility into engine performance, allowing quicker identification and resolution of issues.
Operation-ready jetting unit
The 3-Series is supplied as a complete operation-ready package, with 90 metres of Andy Guest’s ½” single-wire jetting hose, two standard nozzles, a 3m or 5m safety leader hose and lightweight engine and pump cover available as standard with the machine. Operators can opt for an increased water tank capacity of up to 800 litres, with a wide range of compatible accessories, including lance attachments, specialist nozzle kits and surface cleaning equipment also available as optional extras.
Single-person jetting Operations
Single-person operation is made easy via a unique push-button electronic control panel with an electric throttle. Operators can also upgrade to an optional 5-Channel radio remote control or foot pedal due to the plug-and-play characteristics of the unit. Andy Guest’s new radio remote control is supplied as a complete package with a charger, external antenna, transmitter and receiver unit and offers an increased reception range to ensure the safety of contractors in all situations.
Stack drain jetting systems
The 3-Series is also available as a compact and lightweight stack system. Developed for multipurpose CCTV/lining vehicles and the smallest commercial vans, this system offers the same 3000psi @12gpm performance at less than half the width of a traditional van-pack machine to maximise vehicle access, space and payload. The 3-Series stack has a dry weight of 300kg and features a 400-litre (88 gallon) water tank that can be mounted separately for improved weight distribution.
Bespoke jetter configurations
Our non-standard configuration and bespoke jetting machines are continuing to prove a popular choice with customers. The 3-Series can be supplied as a space-saving stack and split system or with a range of upgrades including noise-reducing acoustic covers, increased water tank capacity and high-pressure pump upgrades. We also offer solutions to further maximise vehicle payload, including reconfigured mountings and re-framing using lightweight steel or aluminium.
