Irrigation and Heavy Construction Air Compressors
Irrigation and heavy construction air compressors are high-CFM, gasoline or diesel-driven portable rotary screw units built for well drilling, pipeline blowing, large-bore rock drilling, and sustained multi-tool construction operations. CompressorPros carries portable rotary screw compressors from 70 to 800 CFM from Atlas Copco, ConX, and Elgi. Standard shipping is free.
What Are Irrigation and Heavy Construction Air Compressors?
Irrigation and heavy construction air compressors are large-capacity, diesel-powered portable rotary screw units designed for applications that demand sustained high-volume airflow over extended shifts. These compressors power well drilling rigs, pipeline pigging and blowing operations, large-bore rock drills, multi-tool sandblasting crews, and heavy earthmoving equipment. They deliver 100% duty cycle from 185 to 800+ CFM, far exceeding the output of standard construction portables that typically top out at 185 CFM with a single tool. If your operation requires more than one high-demand tool running simultaneously, or a single tool that draws 200+ CFM, this is the category.
Irrigation vs. Heavy Construction Applications
These compressors serve two overlapping but distinct application environments.
Irrigation and Well Drilling
Irrigation air compressors power pneumatic well drilling rigs, borehole cleaning, and air-lift pumping systems used in agricultural, municipal, and geothermal water well installations. Well drilling operations typically require 185-400 CFM at 100-150 PSI for sustained periods, often running 8-12 hours per day in remote rural locations. Reliable diesel power and towable mounting are essential since these sites rarely have electrical infrastructure.
Heavy Construction and Infrastructure
Heavy construction compressors serve large-scale building, road, bridge, tunnel, and pipeline projects where multiple pneumatic tools run simultaneously. These include multi-hammer foundation work, large-bore rock drilling, pipeline blowing and testing, and crew-scale sandblasting operations. CFM requirements can range from 250 to 800+ depending on the number of tools and the bore size of drills and blasting nozzles.
Types of Irrigation and Heavy Construction Air Compressors
70 - 110 CFM Gas and Diesel Powered Air Compressors
ConX makes smaller rotary screw air compressors that are ideal for irrigation winterizing and other applications where you do not need the power of a 185 CFM air compressor. The ConX SC70 is the number one selling air compressor in this space.
185 CFM Diesel Tow Behind Compressors
The entry point for heavy construction work. A 185 CFM unit powers a single well drilling rig, one large jackhammer, or a medium-bore rock drill with headroom. The Elgi D185T4F 185 CFM Portable Rotary Screw Air Compressor - Tow Behind is the most-searched unit in this range with 58 organic clicks. The ConX SC185DT 45 HP Diesel 185 CFM Tow Behind Rotary Screw offers a compact alternative from a different manufacturer.
250-300 CFM Diesel Tow Behind Compressors
Mid-range units for operations running multiple tools simultaneously or a single high-demand tool that exceeds 185 CFM. The Atlas Copco XATS 250 KD8 65 HP Diesel Tow Behind Air Compressor delivers 250 CFM from a proven industrial diesel platform. The Elgi D300T4F 290 CFM Portable Rotary Screw Air Compressor - Tow Behind pushes close to 300 CFM for crews that need additional headroom.
400-800 CFM Diesel Tow Behind Compressors
The upper tier for large-scale infrastructure projects, multi-hammer pile driving, simultaneous crew sandblasting, and high-volume pipeline work. The Atlas Copco XAS 400-150 PACE 148 HP Tow Behind Rotary Screw Air Compressor delivers 400+ CFM with PACE variable-speed technology for fuel savings during partial loads. Elgi D-series models extend the range to 800 CFM for the most demanding applications.
Key Specifications
- CFM (Cubic Feet per Minute): Irrigation and heavy construction compressors deliver 70-800+ CFM. A well drilling rig typically draws 185-350 CFM. A large-bore rock drill draws 250-400 CFM. Multi-tool sandblasting crews can require 400-800 CFM depending on nozzle count and bore size.
- HP (Horsepower): Ranges from 45 HP at 185 CFM to 200+ HP at 800 CFM. All units in this category are diesel-powered.
- Engine Type: Kubota and Kohler, or similar industrial diesel engines rated for continuous-duty field operation at sustained loads.
- Max PSI (Pounds per Square Inch): Most units deliver 100-150 PSI. Some models offer configurable pressure settings for applications that require higher working pressure.
- Fuel Type: Diesel exclusively at this capacity range. Diesel engines provide the fuel economy, torque, and durability required for 8-12 hour shifts under continuous load.
- Towing/Mounting: Most units in this category are tow behind on single-axle or dual-axle trailers. Some 185 CFM models are also available in skid mount for truck bed transport.
Brands Carried
- Atlas Copco: X-Air, XAS and XATS series diesel tow behind compressors from 185 to 400+ CFM, featuring PACE variable-speed technology that adjusts engine speed to match air demand, reducing fuel consumption during partial-load operation.
- Elgi: D-series diesel portable rotary screw compressors from 185 to 800 CFM in tow behind and skid mount configurations, covering the widest CFM range in this category.
- ConX: Diesel tow behind and skid mount compressors at 185 CFM, known for durable portable rotary screw air compressors.

FAQ
What size compressor do I need for well drilling? Most pneumatic well drilling rigs require 185-350 CFM at 100-150 PSI, depending on bore diameter and formation hardness. A 185 CFM unit handles most residential and agricultural wells. Deeper or larger-bore commercial wells may require 250-350 CFM. Consult your drill manufacturer's specifications for exact CFM and PSI requirements.
What is the most common mistake when buying an irrigation or heavy construction compressor? Not accounting for altitude and temperature. Diesel compressors lose CFM output at higher elevations and in extreme heat. If you operate at altitude or in hot climates, select a compressor rated 10-15% above your calculated CFM requirement to compensate for this.
How many tools can a 400 CFM compressor run at once? A 400 CFM compressor can typically run two 185 CFM jackhammers simultaneously, or one large rock drill plus a secondary tool. The exact number depends on each tool's CFM draw at the required PSI. Add up all simultaneous demands and verify the total is below the compressor's rated output.
How long can these compressors run continuously? All units in this category are rated for 100% duty cycle, meaning they can run nonstop throughout the workday. Runtime per tank of fuel depends on engine size and load. Most 185 CFM units run 8-10 hours on a full tank at rated load. Larger units may require more frequent refueling.
What maintenance do irrigation and heavy construction compressors require? Engine oil and filter changes every 250-500 hours per the engine manufacturer's schedule. Rotary screw airend oil and filter service every 1,000-2,000 hours. Air/oil separator replacement at 4,000-8,000 hours. Daily checks should include fuel, coolant, air filter, and belt condition.
Does CompressorPros offer free shipping on these compressors? Yes. Standard shipping is free, direct from the manufacturer, on every unit in this category.
