Difference Between Pognova Floor-standing Vacuum Sealer EV41 EV51
While these two externally sourced models bear a resemblance to one another, they exhibit distinct differences in performance. The EV51 features a longer sealing bar and a taller vacuum chamber than the EV41, thereby accommodating a wider range of materials. In terms of throughput, the EV51 is also capable of sealing a greater number of bags per cycle. Consequently, it is well-suited for suppliers with higher production volume requirements.

About Pognova Floor-standing Vacuum Sealer EV41
The EV41 Floor-standing Vacuum Sealer features a chamber capacity of 421 x 440 x 120 mm and a sealing length of 400 mm. Being more compact than the EV51 model, it is particularly well-suited for small-scale food service operations and for packaging narrower food items; furthermore, its small footprint ensures greater operational flexibility.
About Pognova Pognova Floor-standing Vacuum Sealer EV51
The EV51 Floor-standing Vacuum Sealer features a chamber capacity of 522 x 522 x 135 mm and a sealing length of 500 mm. Larger than the EV41 model, it is particularly well-suited for packaging wider food products and for large-scale production operations.
How To Choose The Right Model For You
First, you need to determine the dimensions of the food items you typically package, as well as the size of your packaging bags; this will enable you to conduct an initial selection based on your budget. If you need to process larger food items or frequently switch between different types of products, we recommend the EV51, as it offers greater flexibility during actual operation. Conversely, if your products are relatively standard in nature and smaller in size—and you are working with a limited budget—we recommend the EV41.

The vertical vacuum packaging machine is primarily suited for small-scale factories facing significant space constraints; its vertical roller design allows for greater flexibility in adapting to different layouts, thereby enabling more agile production operations. This equipment is specifically engineered for the vacuum packaging of solid, liquid, powdered, or paste-like products, offering a wide range of applications.
Yes. This is one of the single-chamber machine’s greatest advantages.
Principle: Unlike household external-suction vacuum machines (which require expensive textured bags), a single-chamber machine evacuates the air from the entire chamber during operation, thereby equalizing the pressure both inside and outside the bag.
Cost: You can use more affordable commercial smooth vacuum bags (such as PE/PA laminate bags). For users with high-volume packaging needs, this results in significant savings on consumable costs.
The vacuum pump is the heart of the machine; therefore, regular oil changes are crucial:
Recommended Interval: It is generally recommended to change the oil after every 500 to 800 cumulative hours of operation.
Observation Window: The simplest method is to check the oil sight glass located on the side of the machine. If the lubricant turns milky-white (due to moisture ingress) or dark brown (due to oxidation/degradation), it must be changed immediately—even if the scheduled interval has not yet been reached—otherwise, it will damage the pump body and compromise the vacuum level.
Seal quality depends primarily on the “sealing time” and “cooling time” settings:
Scorching (Overheating): The sealing time is set too long, or continuous operation has caused the heat-sealing bar to overheat.
Weak Seal (Incomplete Seal): The sealing time is too short, or there are oil stains or residues on the sealing cloth (high-temperature-resistant tape).
Single-chamber machines are capable of packaging liquids, but certain precautions must be observed during operation:
Control the Liquid Level: Do not fill the bag with liquid beyond two-thirds of its total volume; this prevents the liquid from overflowing the bag opening due to the “boiling effect” that occurs during the vacuuming process.
Use a Slanted Insert: If packaging smaller bags of liquid, you can place a slanted insert (ramp) inside the chamber to elevate the bag opening relative to the bottom, thereby preventing liquid spillage and ensuring the sealing area remains dry.
Although the single-chamber machine is designed for commercial use, proper heat management remains essential:
Operational Efficiency: The machine operates on a “load-vacuum-unload” cycle, capable of completing approximately 2 to 3 cycles per minute.
Thermal Protection: During high-frequency, continuous sealing operations (such as working uninterrupted for several hours), the sealing bar will accumulate heat. It is recommended to allow for brief intervals between large batches of tasks, or to ensure that the chamber’s sealing gasket and sealing cloth remain in good condition, in order to maintain optimal heat dissipation and sealing performance.
