Introduction
Often powered by electric motors, air compressors are used in various industries. These machines work by converting ambient gas into highly pressurized air. Since these devices transfer gas from one location to another, they often have a compressed air filter dryer to remove dust particles, debris, and other contaminants from the air before it enters the compressor.
It is essential that you invest in a compressed air filter in the Philippines because these devices enable proper compressed air preparation. It can even prevent seals from swelling and sustaining premature wear, which helps reduce your downtime and overall expenditures.
At Compresstech Resources, Inc., we can provide you with a range of air tools, including air compressor filters, regulators, and lubricators. Before you go and purchase a specific filter for your system, make sure to determine which of the following types would be ideal for you:
Coalescing Filters
There are quite a few things you need to know about coalescing filters before deciding if your machine requires them. First, these devices are usually available with a manual or an automatic drain option. The former usually requires a minimum of 0.35 bar or 5 psi to close, while the latter must be checked regularly.
You must also note if the model you’re eyeing has a visual service indicator. Most coalescing filters have lights that flash red or green to indicate that something needs replacing. Here are a few more things you should know before deciding what to install along with your air dryer filter:
Working Principle
By forcing gas through an element, coalescing filters can fulfill their purpose. The oil in the air coalesces or sticks together when it changes direction and bumps into itself. Afterward, the substance is caught on an outer sock before it is forced down into an attached bowl by gravity. These waste products must be properly disposed of to avoid any contamination in the system.
Purpose
Coalescing filters are used in compressed air systems to remove oil droplets and fine particles with a size of up to 0.01 micron. Since unwanted oil tends to stick to moving parts and slow the movement of pneumatic cylinders, these components play an integral role in the system.
Types
These types of compressed air filters in the Philippines are either made of metal or polycarbonate. The former can be exposed to lower temperatures and higher pressures than the latter. Furthermore, a polycarbonate model can’t be used alongside incompatible substances as doing so will affect its performance.
Applications
There are various applications of coalescing filters. These devices are commonly used in paint spraying, food preparation, and paper manufacturing. Additionally, they are often used alongside fittings, tubing, and brackets to ensure that the air compressor is in optimum condition.
Vapor Removal Filters
Following a regular maintenance schedule for your compressor’s filter dryer is integral to ensuring optimum working conditions. Since it is only natural that these components get worn down over time, it is also best to err on the side of caution and replace them as often as needed. Some companies even opt to change their filters every other week or month to ensure that the quality of the supplied air meets their standards.
Working Principle
These filters remove vapors in the air that their coalescing counterparts could not. Once gas passes through their cartridges that contain carbon material, it will be virtually free of oil and hydrocarbons from alcohols, esters, and ketones. There are also additional components you can get, such as an extended bowl, to allow more airflow.
Purpose
Some vapors and liquids are harmful to your compressor. This is why many invest in vapor removal filters to ensure that their machines aren’t exposed to substances that can break down their inner workings and compromise the quality of their output. If not monitored properly, a damaged filter element can significantly affect the energy consumed by a compressor.
Types
Vapor removal filters on the market nowadays use different desiccant types. This includes activated carbon, molecular sieves 4A and 13X, silica gel, potassium permanganate, hopcalite, copper sulfate, and more. Although each has the same working principle, some types are preferable for specific substances.
Applications
Specific industries, such as food processing, electronics, and instrumentation, require air with a specific purity. These sectors are often monitored by a governing body since the use of contaminated gas can significantly impact the health and safety of customers who purchase items made from this substance. Therefore, they also require that an adsorbing filter is preceded by a particulate and coalescing filter.
Dry Particulate Filters
Since debris, dust, and other matter restrict airflow due to clogged passageways, these solid particles also affect pressure to a certain extent. This is where dry particulate filters come in. These components can be used as a pre- or post-filter for dryers since they work efficiently during either phase.
Working Principle
There are different stages that air goes through within a dry particulate filter. Larger dust and debris are directly blocked by the fibers in the filter media. On the other hand, smaller particles are intercepted through the Brownian motion (or diffusion) as they erratically move through the component. Additionally, the dry matter is held in the media using electrostatic attraction.
Purpose
A dry particulate filter helps remove solid particles from a gas or fluid. This includes dust, liquid mist, and even microorganisms like bacteria and viruses. Later, you can use them to remove any corrosion particles in your machine caused by time and usage.
Types
Overall, there are three types of particulate filters: P1 has the lowest efficiency rate, P2 has a medium efficiency rate, and P3 has the highest efficiency rate. The size of the particles removed depends on the grade of the filter element you have, so depending on your needs, you can get a model that has efficiency micron grades from 0.1 to 200.
Applications
Many dryer filter units are used in industrial applications to ensure safe and clean products. Key sectors with these components in their dryer systems include food and beverage processing, pharmaceuticals, petrochemicals, and energy production.
