Abstract
A modular filtration column for use with a ductless fumehood, the modular filtration column comprising: a plurality of cassettes having an identical footprint; at least one of the cassettes being configured to move air through the modular filtration column; at least one of the cassettes being configured to filter air moving through the modular filtration column; and at least one seal mechanism for providing an air-tight seal between adjacent cassettes, wherein the at least one seal mechanism is configured to form an air-tight seal devoid of any external compressive force.
Claims22
A modular filtration column for use with a ductless fumehood, the modular filtration column comprising:
- a plurality of cassettes having an identical footprint;
- at least one of the cassettes being configured to move air through the modular filtration column;
- at least one of the cassettes being configured to filter air moving through the modular filtration column;
- and
- at least one seal mechanism for providing an air-tight seal between adjacent cassettes, wherein the at least one seal mechanism is configured to form an air-tight seal devoid of any external compressive force.
An air treatment system comprising:
- a ductless fumehood;
- and
- a modular filtration column for treating air entering and/or exiting the ductless fumehood, the modular filtration column comprising:
- a plurality of cassettes having an identical footprint;
- at least one of the cassettes being configured to move air through the modular filtration column;
- at least one of the cassettes being configured to filter air moving through the modular filtration column;
- and
- at least one seal mechanism for providing an air-tight seal between adjacent cassettes, wherein the at least one seal mechanism is configured to form an air-tight seal devoid of any external compressive force.
A method for filtering air entering and/or exiting a ductless fumehood, the method comprising the steps of:
- determining the material to be filtered from the air entering and/or exiting the ductless fumehood;
- determining the rate of flow of the air entering and/or exiting the ductless fumehood;
- providing a modular filtration column for treating air entering and/or exiting the ductless fumehood, the modular filtration column comprising:
- a plurality of cassettes having an identical footprint;
- at least one of the cassettes being configured to move air through the modular filtration column;
- at least one of the cassettes being configured to filter air moving through the modular filtration column;
- and
- at least one seal mechanism for providing an air-tight seal between adjacent cassettes, wherein the at least one seal mechanism is configured to form an air-tight seal devoid of any external compressive force;
- wherein the number and capacity of the cassette(s) configured to move air through the modular filtration column is in accordance with the determined rate of flow of the air entering and/or exiting the ductless fumehood;
- and
- wherein the number and type of the cassette(s) configured to filter air moving through the modular filtration column is in accordance with the determined material to be filtered from the air entering and/or exiting the ductless fumehood.
