Use this hub to find the right liquid filtration guide and prepare the information needed for product selection or an RFQ. Start with filter bag fundamentals, move to material and micron selection, confirm bag size and housing fit, then provide the actual liquid, operating conditions, quantity, and performance target for technical review.
Start With the Right Liquid Filtration Guide
Understand Liquid Filter Bags
Learn how bag filtration works, what the main components are, and which application details affect product selection.
Liquid, solids type and loading, target retention, flow, temperature, pressure, viscosity, and process objective
Begin with the fundamentals guide.
Which bag material and micron rating?
Chemical compatibility, continuous and peak temperature, particle distribution, nominal or application-defined retention target, and required finish
Use the selection guide and request technical review.
Which standard bag size?
Existing bag dimensions, housing model, basket size, sealing interface, ring style, and connection arrangement
Use the Size #1 vs #2 guide; confirm the actual housing.
What flow or pressure drop should be expected?
Liquid viscosity, clean and loaded differential pressure, housing size, bag area, solids loading, pump data, and allowable process loss
Do not select from a generic flow value alone.
When should the bag be changed?
Differential-pressure trend, process quality, solids loading, run time, cleaning practice, and site operating limit
Set a site-specific changeout criterion; avoid a universal service-life claim.
What belongs in an RFQ?
Product type, bag or housing size, material, micron rating, ring or seal, quantity, liquid, temperature, pressure, flow, and application
Send available drawings, photos, labels, samples, or equipment data.
Product and Housing Paths
When the application inputs are ready, review available liquid filter bag options or industrial filter housings. Product availability and suitability are confirmed against the actual process and equipment rather than inferred from a generic product name.
Frequently Asked Questions
How do I choose a liquid filter bag material?
Start with the liquid chemistry, concentration, continuous and peak temperature, solids, required retention, and process conditions. Material suitability should be reviewed for the actual application; one material is not universally compatible with every liquid.
Does a lower micron number always provide better filtration?
No. A finer rating may increase resistance or shorten the interval before changeout when solids loading is high. Confirm the particle or quality target and whether the stated rating is nominal, absolute, or application-defined before comparing products.
Are Size #1 and Size #2 liquid filter bags interchangeable?
Not automatically. They are different common formats and must match the housing basket, sealing interface, ring style, and installed dimensions. Verify the housing model or measurements before ordering.
Can flow rate or filter bag life be predicted from bag size alone?
No. Flow, pressure drop and changeout interval also depend on viscosity, solids loading, particle distribution, bag media, housing area, pump conditions, temperature, and the site’s operating limit.
What information helps produce a more accurate quotation?
Provide the product type, size or drawing, material, micron rating, ring or seal, quantity, liquid, temperature, pressure, flow if known, and application. Photos, labels, an existing sample, and housing details can reduce specification errors.
