If you own a workshop, you understand the significant impact a reliable air compressor has on your overall workflow. An air compressor is a versatile tool used by both professionals and hobbyists for various tasks—from powering pneumatic tools to inflating tires. If you’re planning to purchase an air compressor and reside in Kenya, this comprehensive guide on air compressor prices in Kenya will help you make an informed decision. Let’s dive straight into the ultimate buying guide.
What is an Air Compressor?
An air compressor” rel=”nofollow noopener noreferrer” target=”_blank”>air compressor is a device that converts power into potential energy stored as compressed air. Unlike other power sources, it stores energy in the form of pressurized air without directly converting heat at the point of use. This compressed air can then be used to power various tools and machinery.
Applications of Compressed Air
Compressed air is highly versatile and is used in many applications including:
- Operating pneumatic cylinders for mechanical movements.
- Rotating shafts for various machinery.
- Generating high-velocity air streams, such as in paint sprayers.
- Powering pneumatic tools like drills, grinders, impact wrenches, riveters, and screwdrivers.
Classification of Air Compressors
Air compressors are typically classified based on their delivery pressure:
- Low-pressure compressors: Deliver up to 150 psi.
- Medium-pressure compressors: Deliver between 151 and 1000 psi.
- High-pressure compressors: Deliver pressures above 1000 psi.
Furthermore, they are categorized based on their working principle:
- Positive Displacement Compressors: These compressors trap a fixed volume of air and reduce its volume to increase pressure. Common types include rotary screws, vane compressors, and reciprocating (piston) compressors, widely used in small to medium-sized workshops.
- Dynamic Compressors: These include centrifugal and axial compressors used in large industrial settings to generate large volumes of compressed air.
How to Choose the Right Air Compressor
- Assess Your Air Tool Requirements:
Understand the pressure and volume requirements of the air tools you plan to use. For example, heavy-duty impact wrenches require higher pressure and volume. Selecting a compressor that’s too small will reduce efficiency and may damage your tools.
Choose Between Tank (Cylinder) and Portable Compressors
Tank-type compressors use an electric motor to compress air and store it in a tank, allowing intermittent use and maintaining pressure. Portable compressors usually lack tanks and operate continuously to deliver air, making them suitable for smaller, mobile tasks.
Consider the Compressor’s Horsepower (HP)
For small to medium applications, air compressors typically range between 1.5 HP and 6.5 HP. Larger HP compressors are generally designed for industrial use. Choosing the right horsepower ensures your compressor can deliver adequate power to your tools without frequent strain.

- Check the Cubic Feet per Minute (CFM) Rating:
CFM measures volumetric airflow and varies with pressure (psi). When comparing compressors with different psi ratings, ensure you consider the Standard CFM (SCFM), which is standardized at 14.5 PSIA, 68°F (20°C), and 0% relative humidity. This measurement helps you accurately compare performance.
Consider Your Power Source
Depending on power availability, select between electric motor-driven compressors or gasoline engine-driven compressors. Electric compressors are ideal for workshops with electricity access, whereas gas-powered units offer portability and convenience in locations without power supply.
Choose the Right Tank Size
If opting for a tank-type compressor, consider the tank size based on your usage pattern. For light, intermittent tasks like nail guns, a smaller tank suffices. However, for long-duration operations, a larger tank helps maintain a steady air supply and reduces motor cycling.

Frequently Asked Questions (FAQs)
What is the average price of an air compressor in Kenya?
The price of air compressors in Kenya varies depending on brand, capacity, and type. Small portable units can start from around KES 10,000, while larger industrial compressors may cost upwards of KES 50,000 or more. For updated pricing, check the market or specific retailer listings.
Which type of air compressor is best for a small workshop?
A reciprocating (piston) compressor with a tank around 24 to 50 liters paired with 2 to 5 HP is typically ideal for small workshops. It delivers sufficient pressure and volume for most pneumatic tools without consuming excessive power.
How do I maintain my air compressor to ensure longevity?
Regular maintenance includes checking and changing the oil (for oil-lubricated models), draining moisture from the tank, replacing air filters, inspecting hoses, and ensuring proper belt tension. Proper upkeep improves efficiency and extends the compressor’s lifespan.
Can I use an air compressor indoors?
Electric air compressors are safe for indoor use with proper ventilation. However, gas-powered compressors should only be used outdoors due to harmful exhaust emissions.
