Types of air filter for diesel generator: A Complete Guide

Introduction

Air filters are an essential part of diesel generators. They prevent dust, dirt, and other harmful particles from entering the engine and causing damage. A dirty air filter can cause engine malfunction, reduced performance, and increased fuel consumption. Therefore, it is essential to choose the right air filter for your generator and clean it regularly. In this article, we will discuss the types of air filters for diesel generators, their functions, how to clean them, and the price range.

Types of air filter for diesel generator

There are two types of air filters for diesel generators: dry and oil bath.

Dry Air Filter for diesel generator

Dry air filters are the most common type of air filter used in diesel generators. They are made of paper, foam, or synthetic materials and are designed to capture large particles, such as dirt and dust. These filters are disposable and need to be replaced after they become dirty. Dry air filters are low maintenance and easy to install, making them the most popular choice among generator owners.

Oil Bath Air Filter for diesel generator

Oil bath air filters are another type of air filter used in diesel generators. They are designed to capture smaller particles and are more efficient than dry air filters. Oil bath air filters are made of a metal or plastic housing, which contains a reservoir of oil. The air that enters the filter is forced through the oil, which traps and removes the particles. Oil bath air filters are reusable and require periodic cleaning and oil changes.

Function of Air Filter in Generator

The primary function of air filters in generators is to prevent harmful particles from entering the engine. The air filter ensures that clean air is supplied to the engine, allowing it to operate efficiently. The air filter also protects the engine from wear and tear caused by dirt and dust. A dirty air filter can restrict the airflow, reduce engine performance, and increase fuel consumption.

How to Clean Air Filter in Generator

Cleaning air filters is an important part of generator maintenance. It helps to ensure that the engine runs efficiently and reduces the risk of damage caused by a dirty filter. Here are the steps to clean an air filter in a generator:

  1. Allow the generator to cool down before turning it off.
  2. Remove the air filter from the generator.
  3. If the filter is a dry air filter, gently tap it against a hard surface to remove any loose dust or dirt.
  4. If the filter is an oil bath air filter, remove it from the housing and drain the oil into a container.
  5. Wash the filter with warm water and a mild detergent.
  6. Allow the filter to dry completely after properly rinsing it with water.
  7. If the filter is an oil bath air filter, refill the housing with fresh oil.
  8. Reinstall the filter in the generator.

Generator Air Filter Price Range

The price of a generator air filter varies depending on the type of filter and the brand. Dry air filters are generally less expensive than oil bath air filters. The price range for a dry air filter is between $5 and $25, while the price range for an oil bath air filter is between $20 and $100. The cost of the filter also depends on the size and capacity of the generator.
