The 5m and 10m options are designed for trough-type channels, tank environments, and warehouse applications where the filter canister needs to be positioned well away from the operator.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the filter canister included with the hose?\u003c\/h4\u003e\n\u003cp\u003eA: No — this listing includes only the extension connecting tube (1× hose).
