Complete Guide to Kobelco SK135SR & SK115SR Air Filter Housing Assembly and Filter Element

8. март 2026.

Historical parts record: Photos and notes below belong to this record. Confirm the offered unit’s full model, condition and available test evidence before ordering.

One air-cleaner housing and filter element are documented in the 5 November 2025 supply entry filed as SK135SR. The photographs show a black cylindrical housing, a mesh-covered element and a removable latched cover. The carton carries QILU/企滤 branding and the label QL-K8015AB, with EC210B/C/D printed as its application. That label differs from the Kobelco SK135SR/SK115SR wording retained in this article's title.

Identification and delivery details

The housing has large round duct openings, a ribbed mounting bracket with four threaded inserts and a split clamping section secured by four spring-loaded screws. With the cover pulled away, a cylindrical element with an expanded-metal outer screen can be seen inside. These are useful matching details when the old housing has cracked or its mounting points differ.

The carton is part of the same photo record, but its EC210B/C/D application must be checked against the intended machine. No readable Kobelco part number is shown. The entry describes one new item; it does not state a warranty. It also contains two weight figures: 6.5 kg in the record field and heading, and 3 kg in the transaction note. Neither is supported by a weighing photograph.

The table follows the physical construction, carton label and original supply entry. No filtration-efficiency test, airflow rating or verified machine fitment is included in this record.

Matching this part

Send the original housing number and photographs of the duct outlets and mounting bracket. Compare outlet diameters, spacing and the element's end seals before accepting the quoted assembly. The SK135SR file name and EC210 carton label should both be included in that check.

Confirm which element and cover are included in the offered set. The photographs show one mesh-covered element; they do not establish a separate inner safety element or a tested filtration standard.
