Delfin High Vacuum Systems FAQ

Home / Blogs

Delfin High Vacuums (DHV) are heavy-duty industrial vacuums designed for high-volume material extraction in demanding environments. Capable of handling hundreds of liters of dense materials, including liquids, DHVs offer powerful suction, easy disposal, and self-cleaning filtration. Ideal for heavy industries, these vacuums enhance efficiency and meet safety standards.

Truly the tank of the industrial vacuum world, heavy-duty vacuums are perfect for heavy industry demands. Between their high-volume capabilities and power, you’d be hard-pressed to find a better option than Delfin High Vacuums (DHV). We’ve put together this FAQ post to help you better understand the utilization and benefits of DHVs. Stick around to learn more.

DHV

What Makes Delfin High Vacuums Heavy Duty?

Our high-performance vacuum cleaners are intended for heavy industries that deal in high volumes of material – hundreds of liters of metals, sand, chips, and others. Heavy-duty vacuums have the voltage necessary to extract high volumes at a high rate, and they also have a high maximum water lift. In other words, what makes them heavy-duty is their capability to extensively extract a wide range of materials (including liquids).

Can I Use a Regular Industrial Vacuum Instead of a Heavy-Duty Vac?

Because these products vary significantly in capability and unique designs, there really is no standard or regular model (technically speaking). But a good alternative to heavy-duty vacuums for anyone seeking a vacuum with serious capabilities while still maintaining portability: a portable industrial vacuum cleaner with three-phase power, significant HP, and medium-to-high volume capacities.

The next question you may want to ask yourself is whether you should use an alternative. DHVs may be worth the investment for anyone in heavy industries with dense material as they can make your operation more efficient and potentially reduce the amount of labor utilized. 

What Is the Capacity for a DHV?

While not every heavy-duty industrial vacuum is built the same, Delfin High Vacuums can contain between 800-1000 liters (or 200-250 gallons) of material. Of course, the weight will vary depending on the material itself, but these vacuums are built with easy disposal and transportation in mind.

How Do I Know What Industrial Vacuum to Use?

There are several factors that have an influence on which industrial vacuum is right for your operation. First, there are federal and industrial regulations that have their impact. If you’re in the concrete industry, for example, your vacuum should be able to properly collect and contain silica particles that are harmful to worker health. 

There’s also combustible dust, long-term efficiency, and whether you require a vacuum with intermittent capabilities or 24-hour cycle capabilities. Start by taking a look at HEPA filtered vacuums and vacuums certified for operation in combustible dust-laden environments.

When to Use a Delfin High Vacuum

Heavy-duty vacuum cleaners like DHVs are unique in that they can withstand demanding, intense environments while containing high volumes of dense materials like sand, metal chips, and even liquids. They also have a time-controlled system that cleans the filters to ensure peak performance amid continuous use.

What Additional Equipment Do I Need?

As is the case with other industrial vacuum cleaners, you can only benefit from additional equipment. A variety of hoses and attachments are a must; navigating different spaces and materials will be made much more difficult otherwise. Note that your DHV operation will also require a forklift or material disposal. See the following question for more details. 

How Do I Dispose of Collected Material From a DHV? 

These large hopper-mounted vacuum cleaners reside above a giant container – but don’t let that intimidate you. The containers are quite easy to detach and maneuver, you simply need access to a forklift and certified forklift operator. 

The forks slide right into the base of the container, from there you may lift and remove the container from the hopper and transport it to the desired vessel. At this point, the container bottom may be easily unlatched and the material discharged until empty.

What Is the Filtering System Like for a DHV?

Self-cleaning for efficiency and durability, the filtering systems in our heavy-duty DHVs consist of polyester felt filter sleeves with internal tensioning springs and a polyester safety cartridge for the pump’s protection.

Pneumatic Vacuum Cleaner: How Air-Operated Industrial Vacuums Work

A pneumatic vacuum cleaner runs on compressed air instead of an electric motor, which is why it holds up better under continuous duty and in wash-down or humid environments. Here’s how the venturi-driven design works and how to size one against your plant’s compressed air line.

Air Powered Vacuum vs Electric Vacuum: Compressed Air Vacuum Cleaners Compared

Air powered vacuums and electric vacuums solve the same problem through completely different mechanisms: one runs on compressed air through a Venturi system, the other on an electric motor. That single difference shapes everything else: energy cost, maintenance, noise, and where each one can legally operate. Neither technology wins outright. An air powered vacuum makes sense in classified locations where electricity itself is the risk. An electric vacuum makes sense for continuous-duty work in ordinary locations. The right choice comes down to your Dust Hazard Analysis, your compressed air setup, and your duty cycle, not a blanket claim that one technology beats the other.

Dust Collection System Design

Dust Collection System Design: from Material Analysis to Safe Commissioning

This guide walks process engineers and facility designers through the complete dust collection system design process in five steps. It starts with material characterization — particle size, combustibility, moisture content — before any ductwork is sized, then moves into CFM calculation using the hood area × capture velocity formula with a worked metalworking example. Section 3 covers ductwork engineering and branch balancing, while Section 4 addresses collector selection, filter media matching, and when to move from portable units to a centralized system. The final section focuses on commissioning verification: three baseline measurements to take at startup and a differential pressure threshold framework to catch performance drift before it becomes a maintenance problem. The article positions Delfin as the only vendor capable of specifying and supplying the full system scope — from portable dust collectors through centralized vacuum systems and pneumatic conveying.

CNC Machine Cleaning

CNC Machine Cleaning: How to Remove Chips, Coolant and Metal Dust Without Downtime

CNC machine cleaning is a mechanical reliability discipline, not just routine housekeeping – chip buildup, contaminated coolant, and metallic dust directly cause spindle damage and unplanned downtime. Standard shop vacs fail almost immediately in machining environments because their filters can’t handle dense metal chips and coolant residue; industrial systems with cyclonic pre-separators are required. Coolant sump maintenance is the most overlooked part of the process: tramp oil contamination and bacterial growth accumulate well before scheduled service intervals and account for roughly 35% of unplanned CNC stops. A solid cleaning protocol runs across three timeframes – daily, weekly, and monthly – covering chip evacuation, nozzle inspection, sump cleaning, and tool changer maintenance. The ideal setup integrates extraction directly into the machining cycle, so cleaning happens continuously rather than competing for scheduled downtime.
