like bag filters, cartridge filters, basket filters, self cleaning filters, self scrape filters,

different types of cartridge and other relevant accessories.

“The Reliable Company” is the basic foundation of CMI. They should be well reflected

throughout our organization and in every aspect of how we do our business, every day. Our

vision is to be preferred partner for solutions in fluid process businesses. This is also to

establish a value of trust. In any organizations, value is always essential to build trust: trust

between our employees, trust between our partners, trust between CMI and society. All CMI

people share a common value as: The Reliable Company.

Sintered Titanium Porous Filters

CMI Titanium Porous Filters are designed for applications

involving heat, gases, aggressive chemicals, cryogenics or

polymers and so on. Made from high purity titanium powder

(99.4%), that is sintered to form a rugged, fixed pore structure.

They can withstand temperature extremes, high pressures and

repeated cleaning/backwash cycles. They have no longitudinal

seams, for improved mechanical strength and corrosion

resistance.

Features

Homogeneous Pore Diameter, Stable Pore Size and High Separation efficiency

High porosity, low filtration resistance, good penetrability

High Temperature resistance: at 280 deg C (wet)

Good chemical durability and corrosion-resistance (PH2-12), anti-oxidation

No particle release, no second pollution to media and meet GMP requirement

Good mechanical property, low differential pressure

Good antimicrobial

Easy clean, online back flush, long lifetime

Good forming technical, more than 1000mm length

No magnetic, nontoxic, widely used in pharmaceutical, food and water treatment
