Basket strainers capture debris in pipelines with a large removable basket. They handle higher flows and larger debris loads than Y strainers, and cleaning is quick.
Basket Strainer Options
- Simplex basket strainers – single basket
- Duplex basket strainers – continuous flow during cleaning
- Quick-opening covers – fast maintenance
- Cast iron, steel, stainless and plastic – match service
- Perforated and mesh baskets – select debris size
Choosing a Strainer
Size for flow and pressure drop, choose basket opening size and select materials for fluid and pressure. DP gauges help schedule cleaning.
Centro supplies basket strainers for water, oil and process lines.

Y strainers are compact inline strainers that protect pumps, valves, traps and meters from debris. They suit steam, water, air, gas and oil lines and can be installed horizontally or vertically.
Y Strainer Options
- Threaded, socket weld and flanged – suit piping
- Bronze, cast iron, steel and stainless – match service
- Screen options – perforated and mesh
- Blow-off connections – flush debris without disassembly
Choosing a Y Strainer
Select by line size, pressure class, material and screen. On steam lines, install with the screen pointing sideways to avoid condensate buildup.
Centro supplies Y strainers for steam, water and process piping.

Industrial filtration protects equipment, products and people by removing contaminants from liquids, gases and air. Clean process fluids extend pump and valve life, improve product quality and help plants meet environmental and safety rules.
Industrial Filtration Categories
- Liquid filtration – bag, cartridge, lenticular and hydraulic oil filters
- Strainers – Y, basket, duplex and automatic strainers
- Filter housings – single and multi-element vessels
- Gas filtration and separation – coalescers, separators and dryers
- Dust filtration – collectors, cartridges, bags and ducting
- Filter presses and automatic cleaning filters – for high solids loads
Choosing a Filtration Solution
Start with the fluid, flow rate, contaminant type and the cleanliness you need. Then weigh first cost against element life and maintenance. Often the best value comes from staged filtration, with a strainer or coarse filter protecting a finer filter downstream.
Centro supplies industrial filtration products from leading manufacturers and can help you choose the right products for an efficient filtration system.

- Industrial filtration is the process of removing unwanted contaminants — solid particles, liquids, gases, and biological material — from air, water, process fluids, and gas streams in manufacturing and processing facilities. It is important because contamination directly impacts product quality, equipment life, worker safety, and regulatory compliance. Without effective filtration, particulates damage pumps, valves, heat exchangers, and instrumentation; airborne dust creates explosion hazards and respiratory risks; and product contamination leads to batch rejection, customer complaints, and regulatory violations. Filtration technologies span a wide range — from simple Y-strainers that catch pipe debris to sub-micron cartridge filters that purify pharmaceutical-grade liquids, from bag filters handling high-volume process streams to coalescing filters that remove oil aerosols from compressed air. The right filtration strategy protects capital equipment, ensures product meets specification, keeps workers safe, and helps facilities comply with EPA, OSHA, FDA, and other regulatory requirements.
- Choosing the right filter starts with four questions: what are you filtering (liquid, gas, air, or steam), what contaminants are you removing (particles, oil, water, biological material), what particle size must be captured (measured in microns), and what flow rate and pressure does the system require? For liquid filtration, bag filters and cartridge filters are the primary options — bag filters handle higher flow rates and larger particle loads cost-effectively, while cartridge filters provide finer filtration down to sub-micron levels. For gas and compressed air filtration, particulate filters remove solid particles, coalescing filters remove oil and water aerosols, and adsorption filters remove oil vapor and odors. For pipeline protection, strainers (Y-strainers and basket strainers) are installed upstream of pumps, valves, and instruments to catch large debris. For airborne dust and particulate, dust collectors with cartridge or bag filtration media capture contaminants at the source. The operating environment, chemical compatibility, temperature, and regulatory requirements further narrow the selection to the correct filter type, media material, and housing configuration.
- A micron rating indicates the size of the smallest particles a filter is designed to capture, measured in micrometers (µm). One micron is one-millionth of a meter — for reference, a human hair is roughly 70 microns in diameter, and bacteria are typically 0.5 to 5 microns. Filters are available from coarse ratings (100–200 microns for large debris) down to sub-micron ratings (0.01–1 micron for fine particulate, oil aerosols, and biological contaminants). Selecting the right micron rating depends on what you are protecting downstream and the quality specification your process requires. A coarse strainer (40–100 microns) upstream of a pump protects the pump from pipe scale and debris. A 5–25 micron bag or cartridge filter in a process line removes visible particulates. A 1 micron or finer cartridge filter is needed for pharmaceutical, food and beverage, or electronics manufacturing applications where product purity standards are stringent. Also consider whether you need a nominal rating (captures a percentage of particles at the stated size) or an absolute rating (captures virtually all particles at the stated size) — absolute-rated filters provide higher assurance for critical applications.
- Filter replacement or cleaning frequency depends on the contaminant load, flow rate, filter type, and how you monitor filter condition. The most reliable indicator is differential pressure — the pressure drop across the filter measured between the inlet and outlet. A clean filter has a low differential pressure; as the filter captures contaminants, the media becomes increasingly restricted and the differential pressure rises. Most filter housings include differential pressure gauges or ports for gauges. When the differential pressure reaches the manufacturer's recommended maximum (typically 15–35 psi for liquid filters, 2–10 psi for gas filters), the filter element should be replaced or cleaned. Operating beyond the maximum differential pressure risks filter bypass, media collapse, or contaminant breakthrough. In practice, many facilities establish a time-based replacement schedule as a baseline (monthly, quarterly, or semi-annually depending on conditions) and supplement it with differential pressure monitoring. Applications with highly variable contaminant loads benefit most from continuous differential pressure monitoring with alarms set at warning and change-out thresholds.
