Two filter factories. One international point of contact.

SantianParts connects international filter buyers with STAL Group manufacturing and coordinated export support.

Manufacturing: Zhejiang Santian and Zhejiang Lifeng

Zhejiang Santian (STAL) and Zhejiang Lifeng (LEFONG) are both part of STAL Group. Both factories support the group’s filter product range.

Santian’s strengths are established equipment and mature production processes. For some orders, LEFONG can offer more flexible delivery arrangements, depending on the order and actual production schedule.

The manufacturing site, technical requirements and delivery arrangements are confirmed for each order.

International sales, orders and export: Guangzhou Topvelsun

Guangzhou Topvelsun coordinates international sales, orders and export communication for SantianParts.

Our business team collects customer requirements and coordinates with the factories and engineers. Formal quotations, substitutions, lead times and custom feasibility are confirmed by the responsible sales or engineering team.
