The Ultimate Guide to Purchasing a Piston Compressor

When it concerns air compression, picking the best compressor is important for numerous markets and applications. Among the myriad options offered, the piston compressor stands apart for its efficiency, dependability, and versatility. This guide intends to inform possible purchasers about the essential factors to consider when acquiring a piston compressor, along with supplying useful comparisons and regularly asked questions.


What is a Piston Compressor?

A piston compressor, likewise referred to as a reciprocating compressor, uses a piston driven by a crankshaft to compress air inside a cylinder. The primary advantage of this kind of compressor is its ability to produce high pressures, making it suitable for applications varying from pneumatic tools to industrial equipment.


Key Considerations When Buying a Piston Compressor

1. Kinds Of Piston Compressors

Piston compressors been available in numerous designs. Buyers should understand the distinctions before making a decision:

TypeDescriptionBest ForSingle-StageCompresses air in one motion of the piston.Small tools and low-pressure applications.Two-StageCompresses air in two phases, leading to higher pressure.Industrial systems needing high effectiveness.Oil-LubricatedUses oil for lubrication, leading to longer life and less wear.Heavy-duty applications where reliability is important.Oil-FreeDoes not utilize oil, making it perfect for clean environments.Food processing, pharmaceuticals, and electronics.

2. Compressor Size and Capacity

Comprehending the needed size and capability for particular applications is essential. The capacity of piston compressors is determined in cubic feet per minute (CFM). The table listed below outlines basic applications and their ideal CFM rankings.

ApplicationSuitable CFMRemarksNail Guns2 - 4 CFMLow usage, normally single-stage.Painting6 - 15 CFMNeeds more air to sustain pressure.Heavy-Duty Air Tools8 - 18 CFMSuitable for two-stage models.Industrial Equipment20+ CFMOften requires large capacities for constant use.

3. Power Source

Piston compressors can be powered by electrical energy, gasoline, or diesel fuel. Each source of power has its advantages:

  • Electric: Often quieter and cleaner, ideal for indoor use.
  • Gasoline: Portable and useful for remote places; nevertheless, can be noisy and produce emissions.
  • Diesel: Excellent for heavy-duty applications however needs more maintenance.

4. Mobility

Depending upon the application, the portability of the compressor may matter. Smaller sized, portable compressors are beneficial for home tasks, while bigger designs are better fit for stationary industrial settings.

5. Noise Level

For applications where noise can be a problem (e.g., woodworking, home usage), consider the sound levels of various models. Sound is normally determined in decibels (dBA):

Noise LevelDescription40 - 60 dBAPeaceful, suitable for indoor use61 - 75 dBAModerate, can be used in workshops76 - 90 dBALoud, may require hearing security
Functions to Look For

When picking a piston compressor, think about the following functions:

  • Tank Size: Larger tanks store more compressed air and offer a longer run time in between cycles.
  • Pressure Control: Adjustable pressure settings enable for varied applications.
  • Safety Features: Look for overload defense, thermal protection, and automatic shut-off functions.
  • Guarantees and Service: A good warranty and accessible customer support can save expenses on repair work and parts.

Frequently Asked Question About Piston Compressors
