CAT CLASS: HQ-10014

100-185 cfm Towable Diesel Air Compressor

Q: Can this size run two 60 lb breakers at the same time?

Typically no. Two breakers often require a combined 160–200+ cfm at full demand, which risks stalling or cycling a compressor at the lower end of this band. The 185-260 cfm class is better suited for dual breaker work.

Q: What distinguishes this class from the smaller <100 cfm units?

The 100-185 cfm range delivers enough reserve capacity to maintain pressure when a second tool is added, whereas <100 cfm units are generally optimized for a single breaker or rotary tool without headroom for concurrent use.

Q: Does this size require a CDL or special trailer endorsement to tow?

Most units in this class fall well below CDL thresholds for weight and do not require commercial licensing when towed behind a standard pickup, though operators should verify local and state regulations.

The 100-185 cfm towable diesel air compressor is a mid-range class designed to power one breaker plus a second pneumatic tool running at the same time. This size sits above the <100 cfm single-tool units and below the 185-260 cfm class that supports three-tool operations. Brands in this segment include Chicago Pneumatic and Atlas Copco.

Spécifications clés

Spécification	Plage typique	Signification
Air delivery	100–185 cfm	Cubic feet per minute output at rated pressure, defining the simultaneous tool capacity.
Operating pressure	100–150 psi	Standard working pressure range for pneumatic breakers and impact tools.
Fuel tank	12–25 gallons	Diesel capacity determines hours of autonomous operation before refueling.
Trailer class	Single-axle, pintle or ball hitch	Road-towable chassis typically under 3,000 lb for maneuvering on confined sites.

Comment choisir

This size class is appropriate when the work requires one pneumatic breaker and a second tool—such as a tamper, impact wrench, or rotary drill—operating concurrently. For single-tool applications or intermittent use of a second hand tool, the Up to 100 cfm Towable Diesel Air Compressor may be sufficient and more economical to transport. When the job calls for two breakers or three tools at once, or when sustained higher-volume applications like sandblasting are planned, the 185-260 cfm Towable Diesel Air Compressor becomes the better choice to maintain pressure and avoid compressor cycling.

Ce que cette taille peut gérer

Pavement breaking with a 60 lb breaker while operating a clay spade or chipping hammer
Trenching and backfilling where a breaker and pneumatic tamper run in sequence or simultaneously
Light demolition on commercial remodels requiring intermittent use of two impact tools
Foundation prep with one breaker active and a backup tool ready without shut-down cycles
Small site utilities work where multiple crew members share the air supply
Road repair with one jackhammer and a handheld grinder or scaler

Sécurité et opération

Shutdown sensors for low oil pressure and high coolant temperature protect the engine under load
Enclosed canopy or roll cage protects rotating and hot components; verify all guards are in place before starting
Ensure tow vehicle and hitch are rated for the compressor's gross weight and tongue load
Grounding and bonding may be required when compressed air is used near flammable atmospheres or coatings

Transport et logistique

Single-axle towable chassis designed for hookup to pickup trucks or service vehicles with standard hitch receivers
Typical gross weight under 3,000 lb permits maneuvering in residential or confined commercial sites
Rigid tow bar or lunette ring configurations available depending on manufacturer and model year

Alimentation

Diesel-fueled engine runs independently; no external electrical connection required on site
Fuel consumption typically 0.5–1.5 gallons per hour under load, depending on tool demand and duty cycle
On-board fuel tank supports 8–16 hours of operation between refills at typical usage rates
