Part Number Index

Yes. Part-number pages sit at a fixed depth in a folder named for the product type rather than the series, so a link stays valid when a series is renamed or succeeded. A retired unit's page stays up too and names its successor, which means a buyer reordering from an old link lands on the current model. Bookmark the part-number page itself, not a search result or a menu page.

Type it as printed on the nameplate into the site search, or open the series page and find it in the table. In the page address, spaces, slashes and the dot in a decimal become hyphens and the brackets drop out, so a voltage shown in parentheses ends up as a trailing code. If a guessed address fails, go to the series page, where every part number in the line is listed with its flow.

Which job the housing is doing. The grade names the element: a 1 micron coalescer belongs ahead of the dryer, a 0.01 micron coalescer after it, and an activated carbon grade at the end of the train for oil vapor. Two housings of the same size and connection but different grades are not interchangeable in service, so order elements by the full part number and check the grade before fitting one.

They are the same size, one air-cooled and one water-cooled. The air-cooled version needs a ventilated room that can absorb its heat; the water-cooled version needs a cooling-water supply and a return, and suits hot, crowded compressor rooms where an air-cooled condenser would derate. Choose the suffix to suit the site rather than the price, because changing later means new plumbing or new ventilation.

Most are. The filters, high-temperature filters, impaction separators, pneumatic and electric drains, bypass valves and the dew point monitor all have full part-number listings on this site. The centrifugal separators, the level-sensing and timed drains and one cycling dryer line are cataloged on a sister site instead, and their series pages here link each part number across. The series index table on this page shows which applies to each line.

Because a corrected duty rarely lands exactly on a rating. With the next size down and the next size up on the same page, you can see at once whether the part number you came to still carries the duty or whether the step up is the safer order, and compare connections and voltage without going back to the series table. The neighbors are also the quickest check that a reorder still suits a plant that has added load.
