If you can provide information about operating conditions (fluid, treatment volume, pressure, operating temperature, and filtration accuracy), we can select the optimal filter element and casing and provide a quote. We can also select only a filter element.
No. Our sales representatives are assigned by area.

Yes, depending on the type of filter element.
Please get in touch, and we’ll have a sales representative contact you.
In general, it’s possible to replace filters as long as they're not special-purpose parts.Please get in touch, and we’ll have a sales representative contact you.
Our Technical Center can carry out small-volume table testing.
With regard to filter service life and other tests, we can provide test-use casings and filter elements for use in on-site field testing.
Yes. If you desire, we can also measure the condition of the filter after cleaning. (Bubble point and airflow resistance measurement)
Sales representatives make regular visits.
Central Maintenance, a group company, offers services including replacement of filter elements as well as system product service for related parts and pressure gauge calibration.
You can either download a catalog from our website or contact us to receive one from a sales representative.
Our Quality Assurance Department tests products before they are shipped.
In the event a customer encounters a problem with a product during use, we will investigate the cause and propose a solution.
※If we are responsible for causing the problem, we will repair or replace the product in question.
Service life varies with the type of filter, filtration precision, and contaminant volume. Although we can suggest a service life as estimated based on past experience, such figures do not constitute a guarantee of filter performance.
Consequently, we recommend field testing if maintenance (element replacement) cannot be easily scheduled.
Because we serve the fine chemical and medical fields, we focus on ensuring products are clean.
Additionally, an extensive track record (and associated expertise) allow us to provide products on a special-order basis that other companies would find difficult to produce.
We draw on the experience with applicable laws and plant projects that we've accumulated since our founding to design and test products while exercising care to ensure that specifications are not excessive with regard to safety.
If you can provide information about your specifications (operating conditions), a sales representative will select the optimal filter and contact you.
For casings, warranty terms are determined at the time of order. However, accidents caused by acts of God such as natural disasters fall outside the scope of warranty coverage.
Other issues not covered by product warranties include use in contravention of design conditions (such as flow rate and temperature), damage resulting from improper storage or maintenance, and modification without consulting with us.
For filter elements, we do not guarantee service life. However, we will replace any filter element that is found to exhibit clear damage or deformation in shape at the time of delivery.
For filter elements, prices vary widely (from hundreds of yen to hundreds of thousands of yen) based on the material and filtration precision.
For casings, prices range from resin products that cost about ¥10,000 to special-order metal products (as needed to satisfy legal requirements or accommodate high pressure levels) that cost more than ¥10 million.
Please get in touch, and we’ll have a sales representative contact you with a filter that meets your operating conditions and its price.
We always strive to lower costs. If you provide information about your current installation, we will propose whatever cost savings we can identify.
There is no fee for quotes.
We’ll discuss the method of payment at the time of order.
It depends on the specifications.
Although it takes about two to three weeks to compile quotes for applications that require legal- or plant-compliant casings, it takes from one day to one week to provide quotes for other applications.
For filter elements, standard products in inventory can be shipped on the same day, but build-to-order elements take about three to four weeks. For casings, standard products in inventory can be shipped in three to four days. Please contact us for more information about delivery times for build-to-order products.
