All trailer configurations are NATM compliant and are offered with an optional toolbox.
An optional jib boom is available on both HX30 model versions, and has exclusive dual articulation, providing the widest range of motion in the industry. A hose restraint helps control the unit’s hose from jumping while working.
An optional power boom is available on the heavy version of the 800-gal HX30 model and features an advanced design that reduces manual labor for the operator. The hydraulically-powered boom offers 330-degree rotation and includes a self-locking gear, acting as a boom brake, to restrain motion of the boom and maintain its desired position.
The machine can be configured to accommodate operator controls on either the left or right side to meet each contractor’s individual needs.

The construction-grade HX30 features a durable, narrow design for easy navigation in urban or congested areas.
Featuring a low-profile design, the machine’s full unit height is reduced. This eases maneuverability and allows the unit to fit in height-restrictive areas, without compromising ground clearance so operators can more easily avoid ground-level obstacles.
An exclusive, hose-storage design allows operators to store the hose flat and straight inside the unit frame?a direct customer-driven enhancement. The vac door also features convenient storage for unit tools, including the vac tube and digging lance.
Patent-pending, advanced door linkage automates lockout when fully opened, without requiring any additional effort from the operator.
The HX30 now has hydraulic controls located at the rear of the units, leaving less opportunity for damage to the unit and enhancing operator visibility.
An optional dual work light features two LED floodlights in the back of the vac unit for use in dark or night conditions.

The HX models feature improved serviceability as all maintenance points are more accessible with a liftoff power pack door design.
Standard on the HX30 is a cyclonic filtration system that minimizes filter cleaning frequency, while providing superior filtration, resulting in increased productivity.
An optional spare tire with a carrier allows easy access to a spare when needed, reducing downtime.
The HX30 has a compact footprint capable of meeting the needs of large-production jobs.
Powered by a 24.8-hp (18.5-kW) Kubota diesel engine, the unit provides optimal suction power and water pressure for any mid-sized underground construction job or other non-hazardous cleanup tasks.
The HX30 provides 66 percent more fuel capacity than its predecessor for improved productivity and fewer refueling stops during the workday.
New, patent-pending make/break seal design optimizes air flow for increased efficiency, and simplified plumbing.
A standard, cyclonic three-stage filtration system cleans the air before it reaches critical components. It is comprised of the debris tank, cyclonic filter and 0.5-micron washable vacuum filter – offering the industry’s best filtration for maximum protection of key components.
Featuring outstanding suction and water pressure, the HX30 is equipped with an efficient 512-cfm (14.5-m3/min) blower, and a powerful water system with water-pressure capacity of 3,000 psi (207 bar) and 4.2-gpm (16-L/min) flow.

Ditch Witch HX30 Vacuum Excavator
The Ditch Witch HX30 is built for utility crews, municipalities, and contractors who need a compact, productive vacuum excavator for potholing, soft excavation, valve box cleanout, and non-hazardous jobsite cleanup. Available through Ditch Witch West, this Ditch Witch vacuum trailer gives crews the capacity, suction, and water pressure needed for mid-sized underground construction work across Alaska, Arizona, California, Hawaii, Montana, Oregon, and Washington.
For crews comparing new vacuum excavators or narrowing their search to trailer vacs, the HX30 is a practical fit when maneuverability, tank capacity, and daily service access all matter.
Ditch Witch HX30 Specs and Jobsite Fit
The Ditch Witch HX30 specs are designed around productive excavation without moving into a larger truck-mounted unit. The HX30 includes a 24.8-hp Kubota diesel engine, 512 CFM airflow, 15 in Hg maximum vacuum, and a water system rated up to 3,000 psi with 4.2 GPM flow.
Configuration options include:
- 500- or 800-gallon debris tank capacity
- 200- or 400-gallon freshwater tank capacity
- 14K, 20K, or 24K GVWR trailer configurations
- 3-inch suction hose
- 6-inch tank outlet valve
- Washable polyester filtration with 73 sq. ft. filter area
- Optional jib boom or power boom on select models
That range gives contractors room to match the machine to utility exposure, restoration limits, towing requirements, and crew workflow.
Why Choose the HX30 Vacuum Excavation Trailer?
The HX30 works well for contractors who need a vacuum excavation trailer that can handle frequent potholing, urban utility work, and cleanup in tighter areas. Its low-profile design helps crews work around congested streets, jobsite access limits, and height-restricted areas.
The filtration system is also a key consideration. The HX30 uses a cyclonic three-stage filtration system to help protect core components and reduce filter cleaning frequency. For crews running daily excavation routes, that can mean fewer interruptions and better uptime.
Ditch Witch West can also help crews compare the HX30 with larger truck vacs, available used vacuum excavation equipment, and related underground construction equipment.
