As more and more users seek efficient, time-saving painting solutions, airless paint sprayers have become the preferred choice over traditional painting methods. The electric airless sprayers, in particular, have gained widespread popularity due to their efficiency and ease of use, offering superior paint application benefits. However, the challenge still exists for many painters especially in after-sale maintenance costs.
With this in mind, HVBAN has focused on manufacturing high-quality, cost-effective airless paint sprayers to enhance painters' productivity and satisfaction. In this article, we'll introduce one of the most popular product lines from HVBAN: the EP Series (Heavy Duty).
The HVBAN EP Series (Heavy Duty) is engineered to handle a broad range of coatings with various tip sizes. Designed for demanding projects, this series excels in heavy-duty applications such as putty, drywall mud, plaster, skim coating, and industrial-grade coatings. Its robust performance ensures users achieve smoother finishes and faster project completion.
The EP Heavy Duty Series includes the EP350, EP450TX, EP850TX, and EP970TX models. Similar to the Portable Series, "EP" denotes Electric Powered, while "TX" signifies an extended pump design.
EP350 The Goalkeeper Between Large and Medium Flow Airless Sprayers
The EP350 offers a flow rate of 4L/min, positioning it at the threshold between large and medium flow airless sprayers. To help you better understand the classification of airless sprayers based on flow delivery capacity, here's a quick guide:
Small Flow Airless Sprayers (Up to 0.5 GPM / ~1.9 L/min):
Characteristics: Compact and lightweight, ideal for detailed work.
Applications: Best suited for indoor projects like cabinets, trim, and small rooms.
Material Compatibility: Handles low-viscosity materials such as stains, lacquers, and enamels.
Medium Flow Airless Sprayers (0.5–1 GPM / ~1.9–3.8 L/min):
Characteristics: Balanced size, suitable for moderate workloads.
Applications: Ideal for residential painting, including interior and exterior walls, fences, and decks.
Material Compatibility: Capable of spraying a range of materials, including latex paints and primers.
Large Flow Airless Sprayers (1–2 GPM / ~3.8–7.6 L/min):
Characteristics: More robust, often equipped with features to handle continuous use.
Applications: Designed for large-scale projects such as commercial buildings and extensive residential properties.
Material Compatibility: Suitable for high-viscosity coatings like heavy latex and smooth elastomerics.
Industrial Flow Airless Sprayers (Above 2 GPM / ＞7.6 L/min):
Characteristics: Industrial-grade machines built for high-demand tasks.
Applications: Used in industrial settings for applications like bridges, ships, and large infrastructure projects.
Material Compatibility: Capable of handling ultra-high-viscosity materials, including elastomerics and block fillers.
If you're unsure about the typical frequency of your painting applications, particularly when transitioning between medium and large-scale projects, the EP350 might be an ideal choice for you.
Key Features of EP350
The key difference between the EP350 and the EP450TX is the pump. The EP350 is designed to handle regular painting tasks with a standard pump, suited for its flow delivery capacity and practical spraying needs, as opposed to the longer pump of the EP450TX.
All airless sprayers with the "TX" suffix at HVBAN indicate that they are equipped with an extended pump. Generally, "TX" pumps are designed for heavy-duty projects or for spraying medium to high viscosity paints. With the extended pump, the machine delivers more power to assist with spraying. You'll notice the difference, especially during heavy-duty projects.
