Types of PECO filters
Coalescing Filters
These filters extract water and other liquids from the petroleum base to protect downstream equipment from damage. For example, PECO coalescing filters separate water from fuels and other fluids used in compressors and other processing equipment.
PECO CPI (Corrosion Prevention Internals)
The CPI filter is a unique filter that protects gas or liquid from contaminants that cause internal corrosion. It protects valve and pipeline internals from corrosive elements by filtering the incoming gas or liquid to produce cleaner fluid. PECO Corrosion Prevention Internals utilize special filter media to capture and reduce transport of corrosive components, maintaining the system's integrity.
PECO MBI (Molecular Basket Internals)
This is a patented filter from PECO that protects downstream equipment from the potentially destructive effects of molecular sieves. The MBI filter reduces the risk that fine particles will escape from depleted molecular sieves and damage downstream equipment. The PECO Molecular Basket Internals features specially designed filter media that provides superb particle filtration without significantly increasing pressure drop.
Dust Filters
PECO dust filters remove solid particles from air to prevent contamination on compressors and other equipment. For example, PECO's high-performance air filters are used to safeguard equipment used in pharmaceutical manufacturing, food processing, and powder handling. PECO dust filter traps particles down to 1 micron in size and is engineered to minimize pressure drop while maximizing particle capture efficiency.
Liquid Filters
These are industrial water filters that provide protection to compressors and other equipment by removing solid contaminants from liquid.
Specification & Maintenance of PECO Filters
Maintenance
- COALESCING FILTER ELEMENT OPERATIONAL CHECK: The PECO filters should be serviced according to operational hours or differential pressure indication, whichever comes first.
- ELEMENT CHANGE OUT: Coalescing filter element should be replaced at least annually, even when in lightly used.
- CLEANING: All internal PECO filter components should be cleaned upon each new filter element change out. The cleaning agent used must not be petroleum-based solvent or harsh chemicals. This is to avoid damage to the filter elements.
- RENEWAL: After cleaning, all internal components should be inspected for wear or damage. Worn and damaged parts should be replaced with original parts.
- ASSEMBLY: The coalescing filter elements must be installed correctly. A clear note is made that PECO filter elements are encapsulated in protective plastic wrapping that must only be removed in a safe and controlled environment where dirt cannot enter the filter elements.
- CHANGE OUT: Ensure that all external and internal connections are re-established.
Specifications of PECO filter
The specifications of filters are parameters such as filter housing, filter types, function, pressure system, and maintenance requirements.
- COALESCING FILTER ELEMENT: it is an all-in-one unit comprising filter mesh and a water collection bowl.
- FILTRATION MEDIA: This is the material the filter is made of. PECO's elements are made of multi-layered, density gradient polypropylene on pleated, stainless steel reinforced. Other elements are made of all-stainless steel.
- INLET/OUTLET: The PECO filter features a 4-inch NPT male inlet and outlet that connect to pipework.
- COLLECTION BOWL: Coalescing filter elements have a water collection bowl located at the bottom of the filter.
- SIGHT GLASS: The glass window used to view the water level within the collection bowl is known as a sight glass. PECO filters have a pressure rating of 100 psi on sight glass, and anything over 100 psi will replace it with a new one.
- DRAIN VALVE: The drain valve is installed in the Coalescer collection bowl. This drains the separated water from the collection bowl. PECO filters use a 3/8-inch NPT male drain valve.
- O-RING: Nitrile O-ring is used on PECO filters to provide a watertight seal when the filter is closed.
- POLYCARBONATE/ALUMINUM: Collection bowls are made from either polycarbonate or aluminum.
- MAX SERVICE PRESSURE: PECO filters can withstand a maximum service pressure of 150 psi and a maximum working temperature of 200°F.
- BASKET FILTER ELEMENT MATERIAL: PECO filter elements are made of all-stainless steel.
How To Choose PECO Filters
Choosing PECO filters involves considering the following factors
- APPLICATION: Choose PECO filter suitable for the application. PECO has different filters designed for air, gas, and liquid service.
- FLOW RATE: Select a filter that can handle the required flow rate for the application. An appropriate filter for the flow rate prevents system pressure from dropping or rising.
- PRESSURE RATING: Ensure the filter can withstand the normal operating pressure in the system. Excess pressure on the filter can cause damage, while insufficient pressure leads to poor performance.
- FILTRATION RATING: This refers to the size of particles the filter can capture. For applications that require high purity, use filters with small micron ratings. Conversely, applications that can tolerate larger particles only require filters with larger micron ratings.
- FILTER MEDIA: PECO filters come with different filter media materials. Each of these materials is compatible with various liquids and gases. Choose a filter based on its compatibility with the fluid in the system.
- HOUSING MATERIAL: Filter housing is made from various materials like stainless steel, carbon steel, and other alloys. Select a filter whose housing material is compatible with the chemical nature of the fluid to be filtered.
- MAINTENANCE REQUIREMENTS: Automated filters require less frequent maintenance. However, non-automated filters will need more frequent maintenance and replacement. Consider this when choosing a filter.
Advantages and Disadvantages of PECO Filters
Advantages of PECO filters
- EXCEPTIONAL FILTRATION: PECO filters have outstanding filtration that efficiently removes contaminants from liquid, air, and gases. This results in improved product quality and system reliability.
- PROTECTION: PECO filter protects downstream equipment and components from damage. This reduces maintenance costs and prolongs the life of machinery.
- VERSATILITY: PECO filters are adaptable for various industrial applications. These include chemical processing, oil and gas, and food and beverage. This makes them suitable for different industries.
- CUSTOMIZATION: These filters can be tailored to meet specific requirements. These include filter rating, size, and housing material. This allows users to get the best filter for their application.
- DURABILITY: PECO filters are built from premium materials and are robust and heavy-duty. They are designed to withstand harsh operating environments.
- EASY MAINTENANCE: Maintenance of PECO filters is straightforward. They are designed for simple filter element replacement and servicing. This saves time and effort for users.
Disadvantages of PECO filters
- INITIAL COST: PECO filters are pricier than conventional filters. Their upfront cost may not be a feasible option for all businesses.
- SIZE AND WEIGHT: Some PECO filters are large and bulky due to being heavy-duty industrial filters. These make them challenging to install in space-constrained areas.
- SPECIALIZED KNOWLEDGE: Selecting and maintaining PECO filters requires specialized knowledge. This may needs trained personnel. Businesses lacking this expertise may face difficulties in filter selection or upkeep.
Q&A
Q. What are PECO filters made of?
A. The coalescing filter element is an all-in-one unit made from multi-layered, density gradient polypropylene on pleated, stainless steel reinforced. This makes the PECO filter very durable and efficient.
