Chemical Propulsion Filters
Protect Mission-Critical Propulsion Systems from Contamination
Mott Chemical Propulsion Filters are engineered to protect launch vehicle and spacecraft propulsion systems from particulate contamination while maintaining high flow rates and low pressure drop. Available in porous metal and mesh configurations, these filters help safeguard turbopumps, feed lines, valves, regulators, ignition systems, and injector elements in the most demanding propulsion environments.

Filtration Technologies
Porous Metal Filters
When fine particle filtration and precise flow control are required, Mott porous metal filters provide highly uniform pore structures that help prevent contaminants from reaching turbopumps, valves, and injector elements. Their rigid sintered construction withstands extreme pressure, vibration, and thermal cycling experienced during launch and flight.
High-Flow Mesh Filters
Mott mesh filters deliver lightweight, high-flow protection for propulsion systems. Designed for cryogenic and high-flow applications, these filters shield critical components from foreign object debris (FOD) while minimizing pressure loss. Mesh designs can be customized for unique propulsion architectures and space-constrained installations.
