Electric/Microcomputer Controlled Vacuum & Gas Flushing Impulse Sealer
Vacuum, Gas flushing & Seal by optimum temperature
"The VG-602 and VG-402 Series features heating-temperature control that makes high-precision vacuum sealing and gas-flush sealing possible.
When you want to flush the air inside the bag and reduce the package volume, or when you want to utilize oxygen scavenger to extend product life, you can use the Vacuum Sealing function.
When you want to fill the bag with nitrogen gas to prevent oxidation, or with carbon dioxide to create bacteriostatic or insect-repellent effects or to prevent spoilage and mold growth, you can use the Gas-flush Sealing function.
The world is full of different things that beg to be packaged.
Go ahead and package to suit your needs with the VG-602 and VG-402 Series!

Basic function and performance
= for all VG-602/402 series
■ Standard equipped with heating-temperature control
Setting the ideal sealing condition
The most prominent feature of the Onpul System is the ability to set and maintain the ideal sealing condition.
The heating temperature setting is made possible through the use of a high-sensitivity temperature sensor for temperature control, and a microcomputer controller.
You can now complete the heating process at just the right temperature for melting the film regardless of the air temperature or fluctuations in the machine temperature.
・ Seal heating temperature setting range: 60 to 250 ℃
・ Seal cooling temperature setting range: Between 40 ℃ and the seal heating temperature Note*
*Note The seal-cooling temperature must be set at a value lower than the user-defined heating temperature setting. If the cooling temperature is set at a value too close to the heating temperature, cooling will not take place and result in the shortening of the life of some parts, including the Teflon part.
■ Easy-to-operate microcomputer controller
The selection and setting of work method and vacuum method, as well as of gas-flush method and its frequency, are all controlled at the microcomputer controller.Simply press the touch panel buttons for the settings.
■ Switch among 13 different sealing methods
The following sealing methods can be combined to create a total of 13 different sealing methods. Select a sealing method to meet your needs, including selecting to best suit the characteristics of the packaged material and to obtain your desired packaging finish.
▼ Work method options
・ Multiple gas flush cycles
・ Vacuum + Seal
・ Seal only
▼ Vacuum method options
・ Vacuum gauge (0 to −100 kPa)
・ Vacuum timer (0 to 99.9 seconds)
・ Manual operation
▼ Gas-flush method options
・ Multiple flush cycles (up to 99 times)
・ Single gas flush
・ Circulating gas-flush (requires piping modification) : Set one of the two nozzles for vacuuming and the other for gas flushing. This will increase the gas-replacement rate by de-airing the bag even as the bag is being filled with gas. Especially effective with soft contents.
▼ Gas flushing timer setting (setting range: 0 − 99.9 sec.)

■ Max. 10 operaetion patterns can be stored
Maximum 10 operation patterns can be stored in the microcomputer controller.Operator can select the stored operation pattern for routine seal work under the same condition setting.
■ Adjustable table height and angle
The height and angle of the table (standard equipment) can be adjusted to suit the package content.
■ Maintenance mode
The state of the machine can be checked by displaying the Maintenance Mode on the LCD screen. Problems can be addressed and resolved at an early stage by checking the blinking areas in the Maintenance Mode and performing any necessary repairs.
The black square in the illustration below indicates a blinking light while the white squares indicate a solid light.
■ Switch to circulating gas flush method
By modifying the piping, it is possible to switch to the circulating gas-flush method. With one nozzle set for gas flushing and the other for vacuuming, the circulating gas-flush method increases gas-replacement rate by de-airing the bag even as it is being filled with gas.

■ Adjustable sealer head angle
The head of the sealer can be adjusted at between 0 and 30 degree angles to suit the package content.
For example, when packaging powders, tilting down the sealer head will allow the sealing to complete without powder spilling from the bag opening.
Adjustments can be made using the hand wheel located on the front panel of the machine.
■ Standard-equipped with air filter and automatic water-drain device
A nozzle-equipped vacuum sealer sometimes may inadvertently take in the bag's contents via the nozzle during the vacuum process.
To counter this problem, the VG-602/402 series comes standard-equipped with air filter to collect foreign objects (liquid, powder, etc.) that were inadvertently taken in during the vacuum process, and prevents the objects from entering into and damaging the vacuum pump.
In addition, by turning on the automatic water-drain device, the foreign objects collected in the air filter can be automatically discharged from the machine after each sealing process.
■ Drive-method two-nozzle mechanism
The horizontal distance between the two nozzles can be adjusted to fit the size of the bag.
Note: The horizontal distance adjustment between the nozzles will not be available if the optional printer FEP-V is installed.
■ Standard-equipped dry filter
The compressed air generated by the built-in compressor sometimes may contain drops of water from condensation, which can enter the machine through the piping and cause damage. To counter this problem, the VG-602/402 series comes standard-equipped with dry filter, which removes drops of water from the compressed air to prevent them from entering into the cylinder and piping inside the machine.
Selective high-performance and high-functionality features
These are the main features and functions that should be considered prior to purchasing the VG-602/402 series sealers.
■ Choose the vacuum pump and drive to fit your needs
You can choose the compressor, which serves as the drive, and the various exhaust-velocity vacuum pump, which serves as the vacuum generator, based on your specific needs, usage environment and package content.

Options
■ 2 line-printing device: Manufacturer option：
Exterior 2-line printing device FEP-V-N2 can be installed as a manufacturer option.
This allows the printing of texts and dates such as "Best before MMDDYY" and "Sell by MMDDYY." FEP-V-N2 is a hot-print-type printer that utilizes heated types to print carbon.
Note: Please note that installation of FEP-V-N2 after the delivery of the main unit requires installation adjustment work by manufacturer or by the reseller.
■ Sealing area cover: Option
The sealing area may be covered using transparent resin (polycarbonate) to help prevent fingers and other objects from getting caught.
■ Long-nozzle specification: Option
Safety Features
■ Equipped with anti-overheating mechanism
When overheating occurs (i.e., when power continues to be distributed to the heating element for longer than 4 seconds), the breaker turns off and the power is shutoff.
■ Equipped with emergency stop switch
In an emergency, press the Emergency Stop Switch to turn off the breaker and shut off the power. This will return the lever to its initial position.
■ Automatic reset upon anomaly detection
When the lever is being pressed down, if a foreign object (e.g., a finger) is caught in the sealing area and is preventing the sealing process from proceeding to the next step, the lever will return to its initial position after one second.
■ Emergency reset operation
When the lever is being pressed down, removing your foot from the footswitch will raise the clamping lever to help prevent fingers and other objects from being caught.
