A gas powered air compressor is a portable, powerful tool that uses a gasoline engine to drive an air compression system, eliminating the need for an electrical outlet. This makes it ideal for remote worksites, construction sites, and any location where electricity is unavailable. Unlike electric compressors, gas models offer unmatched mobility and are built to handle heavy-duty, on-the-go tasks. HPDMC offers two standout options in this category: the 6.5HP Portable Gasoline Power Piston Air Compressor and the 13HP Gasoline Power Piston Air Compressor—each designed to meet specific demands, from medium to heavy-duty applications.


How Does a Gas Powered Air Compressor Work?

At its core, a gas powered air compressor converts gasoline energy into compressed air through a straightforward yet effective process:

  1. Gasoline Combustion: The gasoline engine (e.g., Kohler in HPDMC’s 6.5HP model) burns fuel to generate mechanical power.
  2. Air Intake & Compression: This power drives a piston pump (cast iron in HPDMC models) that draws in ambient air and compresses it into a storage tank.
  3. Pressure Regulation: A pressure switch automatically stops the engine when the tank reaches the maximum pressure (125 psi for HPDMC’s models) and restarts when pressure drops below a set level.
  4. Air Delivery: Compressed air is released through hoses to power pneumatic tools, with flow rates (CFM) determining how many tools can run simultaneously.
  5. This design ensures continuous airflow without relying on electricity, making gas powered compressors indispensable for off-grid work.


Key Types: HPDMC’s 6.5HP vs. 13HP Gas Compressors

HPDMC’s gas powered air compressors cater to different needs, from portable tasks to heavy-duty operations. Here’s how they compare:


1. 6.5HP Portable Gasoline Power Piston Air Compressor

Core Specifications:

  • Power: 6.5HP Kohler gasoline engine (renowned for reliability)
  • Airflow: 11–17 CFM at 125 psi
  • Tank: Compact design (no fixed tank size, optimized for portability)
  • Pump: Single-stage cast iron pump (durable and heat-resistant)
  • Mobility: Wheelbarrow-style design with a dolly structure for easy transport

Standout Features:

  • Ease of Use: Equipped with an auto-start/stop pressure switch and manual lever, simplifying operation for users of all skill levels.
  • Versatility: Can be mounted on service trucks or used as a standalone unit, fitting seamlessly into mobile work setups.
  • Low-Maintenance: Finger valves and a direct-drive system reduce upkeep needs, ideal for busy worksites.


2. 13HP Gasoline Power Piston Air Compressor

Core Specifications:

  • Power: 13HP gasoline engine (double the 6.5HP model for heavy loads)
  • Airflow: Higher CFM output (optimized for multiple tools)
  • Tank: 30-gallon ASME-certified tank (safe for industrial use and continuous operation)
  • Pump: Industrial-grade cast iron cylinders with precision bearings and a finned copper intercooler (reduces heat for longer runtime)
  • Design: Rugged, professional build with enhanced cooling for 24/7 use

Standout Features:

  • Heavy-Duty Performance: Handles simultaneous use of high-airflow tools (e.g., spray foam machines, jackhammers).
  • Durability: Lightweight aluminum connecting rods and removable cylinders make maintenance straightforward, even in harsh conditions.
  • Safety: ASME-certified tank meets strict pressure vessel standards, critical for commercial and industrial settings.


Applications: Where Gas Powered Air Compressors Excel

Gas powered air compressors shine in scenarios where electricity is scarce or mobility is key. HPDMC’s models target specific use cases:


6.5HP Model: Medium-Duty Mobility

  • Worksites: Construction sites, remote repair jobs, and agricultural settings (e.g., livestock farms) where portability is essential.
  • Tools Powered: Pneumatic nailers, impact wrenches, and small paint sprayers (11–17 CFM at 125 psi covers most medium-demand tools).
  • Industries: Light construction, automotive mobile services, and agricultural maintenance (e.g., livestock barn repairs).


13HP Model: Heavy-Duty Professional Use

  • Worksites: Commercial construction, roadwork, and service trucks needing to run multiple tools at once.
  • Tools Powered: Spray foam equipment, large sandblasters, and concrete vibrators (high CFM output supports continuous, high-demand operation).
  • Industries: Industrial construction, commercial roofing, and specialty contracting (e.g., insulation installation with spray foam).


Why Choose HPDMC’s Gas Powered Air Compressors?

HPDMC’s 6.5HP and 13HP models stand out for their reliability, design, and user-centric features:

1. Power & Performance

  • The 6.5HP Kohler engine delivers consistent power for medium tasks, while the 13HP model’s industrial-grade engine handles heavy loads without lag.
  • Both use cast iron pumps—known for heat resistance and long lifespans—ensuring durability in dusty, high-temperature worksites.

2. Mobility & Design

  • The 6.5HP model’s wheelbarrow design lets you maneuver easily across rough terrain, while the 13HP’s rugged build fits securely on service trucks for mobile operations.

3. Safety & Compliance

  • Carbon Monoxide Warning: Both models must be used outdoors (never in enclosed spaces like garages) to avoid CO exposure—a critical safety feature emphasized in HPDMC’s guidelines.
  • Pressure Control: Auto-start/stop switches prevent over-pressurization, and the 13HP’s ASME tank adds an extra layer of safety for industrial use.

4. Warranty & Support

  • Warranty: 1-year full machine coverage and 2-year coverage for core components (pump/airend) for both models.
  • Service: Lifetime maintenance support and a network of air system suppliers ensure quick access to parts and repairs.


Safety Tips for Gas Powered Air Compressors

  • Always Use Outdoors: Gasoline engines emit carbon monoxide—never operate in enclosed spaces (including garages with open doors).
  • Fuel Handling: Refuel only when the engine is cool to avoid fire risks.
  • Maintenance Checks: Inspect hoses and fittings regularly for leaks; replace filters as recommended to keep airflow efficient.
  • Storage: Drain the tank after use to prevent moisture buildup, especially in humid or cold climates.


Choose the Right HPDMC Gas Compressor for Your Needs

  • For portability and medium tasks: The 6.5HP Portable Model balances power and mobility, perfect for small teams and mobile services.
  • For heavy-duty, professional use: The 13HP Industrial Model delivers the airflow and durability needed for commercial projects and multi-tool operations.

Both models redefine what gas powered air compressors can do—combining reliability, safety, and performance to keep your worksite running, no matter where it is.
