The QBH DPF Pressurized Tank Spray Gun is a professional pneumatic fluid-delivery system developed for diesel particulate filter service. Its design combines a refillable pressure reservoir, regulated compressed-air circuit, hand-operated spray control, flexible delivery hose and interchangeable spray probes into one reusable workshop tool.
The system is designed for automotive tool distributors, diesel-service equipment suppliers, fleet workshops and private-label brands looking for a configurable DPF pressurized tank spray gun rather than a disposable aerosol cleaning product.
Product focus: This page concentrates on pressure-tank design, pneumatic fluid delivery, spray control, probe configuration and OEM options. For the complete cleaning procedure, read How to Use a DPF Cleaning Gun.
Pressurized Tank Architecture for Professional DPF Service
The core of the system is a refillable pressure reservoir. Regulated workshop air pressurizes the tank and moves compatible cleaning or flushing fluid toward the trigger gun, flexible hose and selected spray nozzle.
This separates the main pressure unit from the probe itself, allowing the tank and gun to remain outside confined exhaust areas while the flexible probe reaches the required service opening.

Key Features of the DPF Pressurized Tank Spray Gun
Refillable Pressurized Reservoir
The reusable fluid tank stores compatible DPF cleaning or flushing products and acts as the pressure chamber for pneumatic delivery. The tank-based design is suitable for repeated professional workshop service and B2B tool programmes.
Integrated Pressure Regulator
A dedicated pressure regulator controls the incoming compressed-air supply before it reaches the fluid reservoir. This gives the operator better control than connecting an unrestricted workshop airline directly to the spray system.
Pressure Gauge Monitoring
An integrated gauge gives the technician a clear visual reference for the pneumatic supply during use. The correct operating range should always follow the selected gun configuration, cleaning fluid and service procedure.
Trigger-Controlled Fluid Delivery
The hand-operated trigger controls when cleaning fluid is released, helping the operator apply the product in controlled intervals instead of relying on continuous uncontrolled flow.
Fine Atomized Spray Output
The pneumatic delivery system is designed to produce a distributed spray pattern. This improves fluid distribution through the selected probe and allows different nozzle geometries to be used for different spray directions.
Flexible Transparent Delivery Hose
The transparent hose provides distance between the tank system and the working end of the tool. It supports access in restricted exhaust areas while also allowing fluid movement to be observed during application.
Interchangeable Metal Spray Tips
Different metal spray-tip designs can be supplied to provide different outlet directions and spray patterns. This makes the system easier to configure for different workshop and distributor requirements.
External Compressed-Air Powered
The spray gun operates from a regulated workshop air compressor and does not require an integrated electric pump or rechargeable battery, keeping the core system mechanically simple.
Reusable Workshop Equipment
The tank, trigger gun, hose and spray probes are intended as reusable professional equipment when maintained according to the applicable product and chemical instructions.
OEM / ODM Configuration
QBH can review hose lengths, probe combinations, spray-tip options, air fittings, product labels, packaging and accessory kits for distributors and private-label automotive tool brands.

Tank System Buyer Checklist
When sourcing a professional DPF pressurized tank spray gun, buyers should compare more than the product name or tank appearance. Pressure control, fluid-path materials, hose configuration, spray-nozzle design and after-sales support can affect how well the system fits a workshop or distributor programme.
Buyer Checkpoint
What to Confirm
Why It Matters
Tank Capacity
Usable fluid capacity and available tank configurations
Determines how much compatible cleaning or flushing fluid can be prepared for each service cycle
Rated Pressure
Maximum rated pressure and recommended operating range
Helps ensure the tank, gun and pneumatic components are matched to the intended cleaning system
Pressure Regulator
Adjustable regulator range and control accuracy
Allows the workshop to manage compressed-air input instead of relying on unrestricted airline pressure
Pressure Gauge
Gauge range, readability and replacement availability
Provides a visual reference for pressure monitoring during service
Trigger / Valve
Fluid-control method, valve construction and serviceability
Affects how precisely the operator can start, stop and control spray delivery
Air Fitting
Connector type and compatibility with the target market
Different regions and workshop systems may use different pneumatic fitting standards
Hose Material
Material compatibility with the intended cleaning and flushing fluids
The hose must tolerate the selected chemical system and repeated workshop use
Hose Length
Standard length and OEM customization options
A longer or differently configured hose may improve access around difficult exhaust layouts
Seal Material
Seal material and chemical compatibility
Incorrect seal material can reduce durability when exposed to aggressive cleaning fluids
Probe Design
Flexible or rigid probe options, diameter and working length
Probe geometry affects access through different sensor and service openings
Nozzle Pattern
Available outlet directions and interchangeable spray-tip designs
Different nozzle patterns allow different spray orientations inside confined service areas
Spare Parts
Availability of hoses, seals, gauges, valves, fittings and spray tips
Replaceable wear parts can reduce downtime and extend the service life of the equipment
Kit Configuration
Standard accessories and optional probe or fitting combinations
Distributors can select a configuration that better matches their target workshop customers
OEM / Private Label
Logo, labels, packaging, manuals and accessory customization
Allows distributors and professional tool brands to develop market-specific product programmes
For distributors: A lower purchase price does not always mean a lower total service cost. Compare pressure-system design, replaceable parts, chemical compatibility, probe options and after-sales support before selecting a DPF spray-gun supplier.
Why Choose a Pneumatic Pressurized Tank System?
Reusable Rather Than Disposable
The system is designed for repeated professional service instead of relying on a single-use aerosol container.
Regulated Pneumatic Delivery
The combination of pressure regulation, a fluid reservoir and trigger control creates a more configurable workshop delivery system.
Flexible Access
The hose-and-probe arrangement allows the pressure tank to remain outside confined areas while the spray tip is positioned closer to the required service point.
B2B Configuration Options
Different hoses, probes, nozzle sets, air fittings, packaging and branding can be discussed for distributor and OEM projects.
