KD311 Hot-Air Straightening Brush
The K·SKIN KD311 is a corded hot-air straightening brush with independently controlled airflow and PTC heated-brush functions. Brands and importers can evaluate this platform for home-use styling ranges, with electrical specifications, packaging and private label options confirmed for the selected version.
- Separate airflow and heated-brush functions in one corded format
- Three heated-brush settings, separate from the airflow mode selector
- Sample evaluation before electrical, branding and packaging approval
Hot-Air Brush Applications & Product Fit
Compare the product format, operating controls and intended home-use application with the requirements of your styling-tool range.
Hot-Air Styling Format
Consider this format when your range needs an airflow function alongside heated-brush styling. Confirm the permitted hair condition and operating sequence for each function in the manual supplied with the sample.
Independent Operating Controls
Evaluate whether separate airflow and heating controls suit your intended users. Check control labeling and operation on the sample before preparing retail descriptions or packaging artwork.
Home-Use Product Ranges
Relevant to brands, importers and distributors evaluating home-use hair styling tools. The reviewed instructions specify personal home use; B2B supply does not establish suitability for continuous salon operation.

Airflow, PTC Heating & Independent Controls
Understand the airflow path, heated comb and separate controls before selecting the sample version. Describe additional features only within the scope supported by its specification.
Airflow System & Outlet Design
The airflow system directs air through the brush outlets. A separate selector provides Off, Air, Low and High positions. Confirm their labeling and operation against the instructions for the supplied version.
PTC Heated Straightening
The reference heated-brush function offers 160°C, 180°C and 200°C settings. These refer to the heated comb settings, not the temperature of the outlet air; measured behavior depends on the agreed test conditions.
Independent Heat & Airflow Controls
Separate switches control the airflow system and PTC heated brush. Evaluate each function and any permitted combined routine against the selected version’s operating instructions.
Brush Construction & Version-Specific Features
Review the comb teeth, bristles, housing and inlet on the supplied sample. Where a negative-ion function is specified, confirm the corresponding configuration; its presence alone does not establish an ion quantity or hair-care outcome.
Hot-Air Brush Sample Evaluation
Record the sample ID, electrical version, manual revision and evaluation conditions. Use the approved specification and sample records as the reference for these six checks. For the evaluation method, see Hair Straightener Brush vs Hot-Air Brush: What Is the Product Difference?.
Airflow Mode Control
- Verify the Off position before operation
- Record switching response and airflow consistency in the labeled modes
- Confirm that airflow control remains independent from straightening-temperature control
Straightening-Temperature Control
- Check all three heated-brush settings against the sample specification
- Record temperature behavior, measurement position and test conditions
- Keep heated-comb measurements separate from outlet-air measurements
Comb, Brush & Hair Handling
- Inspect the dual comb-tooth and brush construction
- Evaluate handling on representative hair samples under permitted conditions
- Record the routine, hair condition and observed styling result
Version Features & Protective Functions
- Match any specified negative-ion function to the sample configuration
- Request protective-function test records from qualified personnel
- Check that the records identify the proposed production version
Electrical Version & Rating Label
- Match model, voltage, frequency and power to the sample rating label
- Inspect cord, plug and strain relief
- Review inlet condition, housing assembly and the cleaning instructions
Physical & Commercial Readiness
- Measure dimensions and net weight against the approved specification
- Review labels, manual and packaging against the approved project version
- Confirm that the electrical version matches the intended market
Private Label Options & Market Configuration
Start with a defined sample and electrical version. Review branding and packaging separately from functional, structural or electrical changes that require engineering evaluation.

KD311 Sourcing Questions
Answers to common questions from brands, importers and buyers evaluating the KD311.
How does the KD311 differ from a heat-only straightening brush?
The KD311 combines an airflow system and a PTC heated brush in one corded format. This gives buyers a different product configuration to evaluate alongside heat-only brushes. It does not by itself establish faster styling, less damage or suitability for every hair type.
Which electrical version should be specified for an order?
Specify the destination market and request the currently offered electrical version. Available reference records include 125 V / 60 Hz at 950 W and 230 V / 50 Hz at 850 W. Confirm the supplied sample, rating label, specification and applicable documents together; these records do not establish current availability for every version.
Are airflow and heated-brush functions controlled separately?
The reference design has separate airflow and heated-brush controls. Check the switches, mode labels and response on the supplied sample. The heated-brush temperature settings do not describe outlet-air temperature, and permitted operating combinations must follow the version-specific instructions.
What private label options can be reviewed?
Review branding, available finishes, packaging artwork, labels and manual language for the selected product version. Electrical, control or structural changes require engineering review. Confirm quantity, cost, lead time and applicable documents for the proposed order.
What hair-condition requirements should buyers confirm?
Do not treat airflow and heated-brush use as the same routine. The reviewed manual contains towel-drying preparation guidance as well as dry-hair restrictions. Request clarified, approved instructions for each function before making wet-to-dry claims or approving product listings.
Which documents and sample details should be checked before approval?
Request the product specification, manual, rating-label details, packing data and available inspection or compliance records. Match model, electrical version, document scope and original holder. Confirm dimensions and weight against the actual sample and resolve any inconsistent records before order approval.
