VAPOR CONTROL SYSTEMS

MODEL 3100/4100

MODEL 3500/4500 The Model 3500/4500 are pressure vents designed to vent the tank vapor away to a header system. The 3500 is a weight loaded style whereas the 4500 incorporates a spring loaded design. One of the key features to the design is that it can be retrofitted in the field to become a 5500 series. If

MODEL 3400/4400

MODEL 3200/4200

The Model 3200/4200 are pressure/vacuum vents designed to vent the tank vapor away to a header system and to relieve vacuum pressure within the tank. The 3200 is a weight loaded style whereas the 4200 incorporates a spring loaded design. One of the key features to the design is it can be retrofitted in the field to become a 5100, or a 5200 series unit. (This does not include FRP Bodies.) This allows facilities to upgrade and meet ever changing EPA standards. (FRP Not available on 4000 Series).

The Model 3400/4400 are pressure vents designed to vent the tank vapor away to atmosphere. The 3400 is a weight loaded style whereas the 4400 incorporates a spring loaded design. (FRP Not available on 4000 Series.)

The Model 3100/4100 are pressure/vacuum vents designed to vent the tank vapor away to atmosphere and to relieve vacuum pressure within the tank. The 3100 is a weight loaded style whereas the 4100 incorporates a spring loaded design. One of the key features to the design is it can be retrofitted in the field to become a 3200, 4200, 5100, or a 5200 series unit. (This does not include FRP Bodies.) This allows facilities to upgrade to meet ever changing EPA standards. (FRP Not available on 4000 Series).

vacuum vent is required, it can also be upgraded to a 3200, 4200, or a 5200 series unit. (This does not include FRP Bodies.) This allows facilities to upgrade to meet tank requirements and ever changing EPA standards. The 3500/4500 can also be used as a side mounted vacuum vent with inlet flange. (FRP Not available on 4000 Series.)

The Model 3600/4600 are vacuum vents designed to allow atmospheric air into the tank to reduce the vacuum pressure in the tank. The 3600 is a weight loaded style whereas the 4600 incorporates a spring loaded design. One of the key features to the design is that it can be retrofitted in the field to become a 3200, 4200, or a 5200 series unit if additional venting is required in the future. (This does not include FRP Bodies.) This allows facilities to upgrade their equipment to meet both plant requirements and ever changing EPA standards. (FRP Not available on 4000 Series.)

The Model 3300/4300 are vacuum vents designed to allow atmospheric air into the tank to reduce the vacuum pressure in the tank. The 3300 is a weight loaded style whereas the 4300 incorporates a spring loaded design. One of the key features to the design is it can be retrofitted in the field to become a 3100, 3200, 4100, 4200, 5100 or a 5200 series unit if additional venting is required in the future. (This does not include FRP Bodies.) This allows facilities to upgrade their equipment to meet both plant requirements and ever changing EPA standards. (FRP Not available on 4000 Series.)
