Frequently Asked Questions (FAQ)

Q1: What are the primary machine applications for 1R-0735?
A1: Suitable for Caterpillar excavators, wheel loaders, and articulated dump trucks requiring heavy-duty hydraulic fluid filtration.

Q2: Why is micro-glass media superior to paper media in hydraulic systems?
A2: Micro-glass fibers possess consistent pore structures that do not soften or swell when exposed to hot hydraulic fluid, delivering steady beta filtration performance throughout its lifecycle.

Q3: What are the payment and lead time terms?
A3: We support T/T, L/C, Western Union, and Alibaba Trade Assurance. Standard production lead time is 7-15 business days.
