Fluid evacuation system with two-way communication filter

1. A method for controlling a system for evacuating suspended particulates from a fluid having at least one fluid intake, at least one fluid outlet, a first read/write device, and a controller coupled to said first read/write device, said method comprising:

inserting a filter into said evacuation system, said filter having a rated filter life and said filter including a RFID tag having said rated filter life stored thereon;

transmitting said rated filter life from said RFID tag to said first read/write device;

measuring the flow into said filter;

operating said evacuation system for a first time period;

determining remaining filter life by subtracting said first time period from said rated filter life; and

adjusting said remaining filter life with said controller as a function of said flow into said filter;

wherein said remaining filter life is calculated as a function of flow into said filter and as a function of time.

2. The method according to claim 1 further comprising displaying said remaining filter life on a display screen coupled to said controller.

3. A method for controlling a system for evacuating suspended particulates from a fluid having an RFID tag reader and a controller coupled to said RFID tag reader, said method comprising:

inserting a filter into said evacuation system, said filter operable only within an established flow range;

said filter having an associated RFID tag which contains information identifying said established flow range;

transmitting said information identifying said established flow range from said RFID tag to said RFID tag reader;

controlling an evacuation motor with said controller such that said evacuation motor operates only within said established flow range.

4. A method for controlling a system for evacuating suspended particulates from a fluid having an RFID tag reader and a controller coupled to said RFID tag reader, said method comprising:

inserting a filter into a first evacuation system, said filter having a rated filter life and said filter having a RFID tag with said rated filter life stored thereon;

measuring the flow into said filter during a first time period;

determining remaining filter life as a function of said flow into said filter;

storing said remaining filter life information on said RFID tag;

removing said filter from said first evacuation system and inserting said filter into a second evacuation system, said filter retaining said remaining filter life information determined in said first evacuation system.

5. A method for controlling a system for evacuating suspended particulates from a fluid having an RFID tag reader and a controller coupled to said RFID tag reader, said method comprising:

inserting a filter into said evacuation system, said filter having an RFID tag for storing filter life information thereon;

measuring the flow of a fluid into said filter during a first time period;

determining remaining filter life as a function of said flow into said filter during said first time period;

storing said remaining filter life on said RFID tag;

determining whether suspended particulates are present in said fluid during said first time period;

if suspended particulates are not present in said fluid during said first time period, resetting said stored remaining filter life to its value prior to said first time period; and

measuring the flow of a fluid into said filter during a second time period.

6. The method according to claim 5 wherein said suspended particulates comprise smoke or moisture.
