Abstract
An inertial separator comprising a tubular body, the tubular body comprises a composition comprising a polymer selected from the group consisting of a cyclic olefin polymer and a cyclic olefin copolymer, and, a polyhedral oligomeric silsesquioxane and/or a flame retardant and/or an anti-static additive, is disclosed.
Claims15
An inertial separator comprising
- a generally tubular body comprising a first end and a second end, an inlet, and first and second generally coaxial outlets, wherein the second end of the body comprises a tapered end comprising the second coaxial outlet, and the first end of the body further comprises the first coaxial outlet, and,
- the tubular body comprises a composition comprising a polymer and a polyhedral oligomeric silsesquioxane and/or a flame retardant and/or an anti-static additive, wherein the polymer is selected from the group consisting of a cyclic olefin polymer and a cyclic olefin copolymer.
An inertial separator comprising
- (a) a tubular body having an inlet at one end, an outlet at the opposite end, and a central passage therebetween, the central passage having a peripheral portion and a central portion;
- (b) a deflector coaxially mounted in the passage, the deflector having a plurality of spaced centrally joined helical vanes abutting the wall of the passage, and positioned at an angle to the line of air flow from the inlet to the outlet, so as to create a vortex stream of influent air centrifugally concentrating contaminant particles in the air at the periphery of the passage, and leaving air at the center of the passage relatively free from contaminant particles;
- (c) a generally coaxial outlet member positioned within the outlet end of the tubular body, the outlet member having an inlet at one end, and an outlet at the opposite end, and a central passage therebetween for delivery of clean air from the central portion of the central passage of the tubular body, the inlet end of the outlet member being of lesser diameter than the central passage of the tubular body;
- wherein the tubular body and the deflector each comprise a composition comprising:
- a polymer selected from the group consisting of a cyclic olefin copolymer and a cyclic olefin polymer;
- and, a polyhedral oligomeric silsesquioxane and/or a flame retardant and/or an anti-static additive.
