Vehicle Exhaust Removal - Firehouse/EMS

1. Diesel Exhaust Removal—Fire Station Retrofit Project

Application: Operation of fire trucks and ambulances inside fire station generated large volumes of diesel smoke. The original ventilation system, consisting of blower, duct work and floor mounted rubber compression fit tail pipe nozzles with cable release mechanism operation, proved to be a cumbersome system to use and fire fighters were only partially protected. The new easy-to-use Plymovent system provided virtually 100% tail pipe seal, reliable automatic tail pipe nozzle release and increased air flow.

Filtration Equipment: Three Plymovent Model SBT-20 Sliding Balancer Track Systems with virtually 100% Tail Pipe Seal Grabber Nozzles, 5 hp Non-sparking Blower; Control Panel; Compressor; Spiral Piping Duct Work

Special Equipment: Blower utilized combination Vertical Discharge / Backdraft Damper

Location: Colorado

Type of Dust/Smoke: Diesel smoke

CFM/Static Pressure: 1650 cfm @ 6" s.p.

Dust/Smoke Load: N/A

Filter Velocity: N/A

Filter Type: N/A

2. Diesel Smoke Removal—AARF Station

Application: Diesel smoke from airport fire station diesel engine exhaust. Vertical stack fire/rescue vehicles generate large volumes of diesel smoke when leaving station. Plymovent VSR and STR rail systems contained smoke and protected fire fighters from airborne smoke and fumes.

Filtration Equipment: Seven Plymovent Model VSR-40 Vertical Stack Rail Systems, including Pressure Sensing Starting Controls; Main Blower for Four VSR Units; Bayley Model EX261GP, 10 hp with Vertical Discharge Combination Backdraft Damper Discharge. Station also used Plymovent Model STR 60 Straight Rail System for drive-through bays.

Special Equipment: None

Location: Colorado

Type of Dust/Smoke: Diesel smoke

CFM/Static Pressure: Each VSR requires approximately 800 cfm @ 4" s.p.

Dust/Smoke Load: N/A

Filter Velocity: N/A

Filter Type: Heavy—AARF engines generate heavy smoke loads because they generally exit stations at high rpm levels.

Filtration Equipment: Five Plymovent SBTA20 Sliding Balancer Track Systems including 7.5 hp Blower, Automatic System Starting Control Panel, and Spiral Ducting System; Blower using Vertical Discharge Design and Backdraft Damper; Tail Pipes Connected with Virtually 100% Positive Seal Grabber Nozzle

Special Equipment: Two SBTA Tracks with Curved Rails

Location: Colorado

Type of Dust/Smoke: Diesel smoke

CFM/Static Pressure: 3500 cfm @ 7" s.p.

Dust/Smoke Load: N/A

Filter Velocity: N/A

Filter Type: N/A

5. Diesel Smoke Removal—Emergency Vehicle Exhaust

Application: Fire trucks generate diesel smoke exhaust inside station house when leaving/entering bays.

Filtration Equipment: Five Plymovent SBT 20, Sliding Balancer Tracks with Virtually 100% Seal Grabber Nozzle; 10 hp Blower; Ducting; Vertical Backdraft Damper; Control Panel

Special Equipment: None

Location: Colorado

Type of Dust/Smoke: Diesel smoke/fumes

CFM/Static Pressure: 2500 cfm @ 7" s.p.

Dust/Smoke Load: Heavy

Filter Velocity: N/A

Filter Type: N/A

6. Diesel Smoke Removal—Fire Station

Application: Ventilation of NEW Fire Station diesel engine exhaust. Plymovent's virtually 100% tail pipe seal "grabber" nozzle isolates fire fighters from smoke buildup when engines are started indoors. System also reduces smoke buildup and deposits on internal station fixtures.

Filtration Equipment: Nine Plymovent Model SBT 20 Sliding Balancer Track Systems, including Automatic Blower Starting Control Panel and Hartzell Model S03P-152BC, 5 hp Blower

Special Equipment: N/A

Location: Colorado

Type of Dust/Smoke: Diesel smoke

CFM/Static Pressure: 4500 cfm @ 7" s.p.

Dust/Smoke Load: Moderate to Heavy, depending on number of engines operating simultaneously.

Filter Velocity: N/A

Filter Type: N/A

7. Drive-Through Fire Station

Application: New drive-through fire station designed with need to utilize different vehicles in same bay and to allow for up to 60’ travel of vehicle exhaust system. Plymovent source capture grabber nozzle attaches direct to engine tailpipe and releases at garage door as engine exits station. The STR (straight rail design) allows for extended vehicle travel while connected to the system thereby isolating operators from ambient diesel smoke exhaust.

Filtration Equipment: Three Plymovent STR-60 Straight Rails, 60’L each; One Plymovent TEV-745-60 10 hp Industrial Blower

Location: Colorado

Type of Dust/Smoke: Diesel engine exhaust

CFM/Static Pressure: 2700 cfm @ 6” s.p.

Dust/Smoke Load: Moderate

8. EMS Ambulance Facility

Application: EMS Ambulance facility required source capture engine exhaust system to fit into low ceiling garage area located under parking garage. Two systems with 10 and 11 hose drops respectively and wall mounted retractable hose drops suspend hose when not connected to ambulance tailpipe. Direct tail pipe connection to engine exhaust isolates operator breathing zones and keeps fumes/smoke from migrating throughout facility.

Filtration Equipment: Twenty-One Plymovent Retractable Hose Drops including Heavy Duty Balancers and Nozzles; Two Plymovent TEV-745-60 10 hp Industrial Blowers

Location: Colorado
